Various application roles for Campbell systematic reviews: a citation analysis
Objectives: Systematic reviews (SRs) are becoming essential evidence in the decision-making process within the field of social sci-ences. This study aimed to investigate how Campbell SRs were cited and explore their specific application roles.Study Design and Setting: We included Campbell SRs published between 2016 and 2020 by searching the Wiley online library, and retrieved the articles and documents citing Campbell SRs from the Web of Science and Google Scholar by December 31, 2021. We described the characteristics of the SRs and citations, and formulated a set of application roles by analyzing the sentences or paragraphs where the SRs were cited.Results: Sixty nine Campbell SRs were published between 2016 and 2020; they were cited in 641 articles or documents a total of 1,289 times. The primary types of articles that cited Campbell SRs were cross-sectional studies (n = 226, 35.3%), SRs (n = 112, 17.5%), ran-domized controlled trials (n = 77, 12.0%), and policy reports (n = 57, 8.8%). Articles utilizing Campbell SRs were predominantly led by authors from the United States (n = 184, 28.7%), the United Kingdom (n = 98, 15.3%), and Australia (n = 51, 8.0%). We formulated a set of 10 application roles for the Campbell SRs, of which the most frequent were: describing the current status in the field of interest (n = 691, 53.6%), corroboration of the results (n = 140, 10.9%), identifying research gaps (n = 130, 10.1%), and providing methodological refer-ences (n = 126, 9.8%); the role of supporting policy recommendations or decisions accounted for 6.0% (n = 77) of the citations. Approx-imately 12% of Campbell SRs were used to support policy recommendations or decisions.Conclusion: Campbell SRs are widely applied, particularly in scientific research, to describe the current status in the field of interest. Although the current application of Campbell SRs in supporting policy recommendations and decisions may not be predominant, there is a growing recognition of their value in using Campbell SRs to inform decision-making.(c) 2023 Published by Elsevier Inc.

Methodological and reporting quality of systematic reviews on health effects of air pollutants were higher than extreme temperatures: a comparative study
BackgroundAn increasing number of systematic reviews (SRs) in the environmental field have been published in recent years as a result of the global concern about the health impacts of air pollution and temperature. However, no study has assessed and compared the methodological and reporting quality of SRs on the health effects of air pollutants and extreme temperatures. This study aims to assess and compare the methodological and reporting quality of SRs on the health effects of ambient air pollutants and extreme temperatures.MethodsPubMed, Embase, the Cumulative Index to Nursing and Allied Health Literature (CINAHL), Cochrane Library, Web of Science, and Epistemonikos databases were searched. Two researchers screened the literature and extracted information independently. The methodological quality of the SRs was assessed through A Measurement Tool to Assess Systematic Reviews 2 (AMSTAR 2). The reporting quality was assessed through Preferred Reporting Items of Systematic reviews and Meta-Analyses (PRISMA).ResultsWe identified 405 SRs (286 for air pollution, 108 for temperature, and 11 for the synergistic effects). The methodological and reporting quality of the included SRs were suboptimal, with major deficiencies in protocol registration. The methodological quality of SRs of air pollutants was better than that of temperature, especially in terms of satisfactory explanations for any heterogeneity (69.6% v. 45.4%). The reporting quality of SRs of air pollution was better than temperature, however, adherence to the reporting of the assessment results of risk of bias in all SRs (53.5% v. 34.3%) was inadequate.ConclusionsMethodological and reporting quality of SRs on the health effect of air pollutants were higher than those of temperatures. However, deficiencies in protocol registration and the assessment of risk of bias remain an issue for both pollutants and temperatures. In addition, developing a risk-of-bias assessment tool applicable to the temperature field may improve the quality of SRs.

The effects of active workstations on reducing work-specific sedentary time in office workers: a network meta-analysis of 23 randomized controlled trials
BackgroundActive workstations have been proposed as a feasible approach for reducing occupational sedentary time. This study used a network meta-analysis (NMA) to assess and compare the overall efficacy of active workstation interventions according to type and concomitant strategy for reducing work-specific sitting time in office workers.MethodsPubMed, Web of Science, EMBASE, and Cochrane Central Register of Controlled Trials (CENTRAL) databases were searched from database inception until May 2022 to obtain randomized controlled trials (RCTs) assessing the efficacy of active workstations with or without concomitant strategies for reducing occupational sedentary time in office workers. The risk of bias of the RCTs included in this study was assessed according to the Cochrane Handbook. An NMA with STATA 15.1 was used to construct a network diagram, league figures, and the final surface under the cumulative ranking curve (SUCRA) values. The certainty of evidence was assessed using the grading of recommendations, assessment, development, and evaluation (GRADE) approach.ResultsA total of 23 eligible studies including eight different types of interventions with 1428 office workers were included. NMA results showed that compared to a typical desk, multicomponent intervention (standardized mean difference (SMD) = - 1.50; 95% confidence interval (CI) - 2.17, - 0.82; SUCRA = 72.4%), sit-stand workstation + promotion (Reminders of rest breaks, posture variation, or incidental office activity) (SMD = - 1.49; 95%CI - 2.42, - 0.55; SUCRA = 71.0%), treadmill workstation + promotion (SMD = - 1.29; 95%CI - 2.51, - 0.07; SUCRA = 61.6%), and sit-stand workstation (SMD = - 1.10, 95%CI - 1.64, - 0.56; SUCRA = 50.2%) were effective in reducing occupational sedentary time for office workers.ConclusionsMulticomponent intervention, sit-stand workstation + promotion, treadmill workstation + promotion, and sit-stand workstation appear to be effective in reducing work-specific sedentary time for office workers. Furthermore, multicomponent interventions and active workstations + promotion better reduced work-specific sedentary time than active workstation alone. However, the overall certainty of the evidence was low.

Comprehensive evaluations of individual discrimination, kinship analysis, genetic relationship exploration and biogeographic origin prediction in Chinese Dongxiang group by a 60-plex DIP panel
BackgroundDongxiang group, as an important minority, resides in Gansu province which is located at the northwest China, forensic detection system with more loci needed to be studied to improve the application efficiency of forensic case investigation in this group.MethodsA 60-plex system including 57 autosomal deletion/insertion polymorphisms (A-DIPs), 2 Y chromosome DIPs (Y-DIPs) and the sex determination locus (Amelogenin) was explored to evaluate the forensic application efficiencies of individual discrimination, kinship analysis and biogeographic origin prediction in Gansu Dongxiang group based on the 60-plex genotype results of 233 unrelated Dongxiang individuals. The 60-plex genotype results of 4582 unrelated individuals from 33 reference populations in five different continents were also collected to analyze the genetic background of Dongxiang group and its genetic relationships with other continental populations.ResultsThe system showed high individual discrimination power, as the cumulative power of discrimination (CPD), cumulative power of exclusion (CPE) for trio and cumulative match probability (CMP) values were 0.99999999999999999999997297, 0.999980 and 2.7029E(- 24), respectively. The system could distinguish 98.12%, 93.78%, 82.18%, 62.35% and 39.32% of full sibling pairs from unrelated individual pairs, when the likelihood ratio (LR) limits were set as 1, 10, 100, 1000 and 10,000 based on the simulated family samples, respectively. Additionally, Dongxiang group had the close genetic distances with populations in East Asia, especially showed the intimate genetic relationships with Chinese Han populations, which were concluded from the genetic affinities and genetic background analyses of Dongxiang group and 33 reference populations. In terms of the effectiveness of biogeographic origin inference, different artificial intelligent algorithms possessed different efficacies. Among them, the random forest (RF) and extreme gradient boosting (XGBoost) algorithm models could accurately predict the biogeographic origins of 99.7% and 90.59% of three and five continental individuals, respectively.ConclusionThis 60-plex system had good performance for individual discrimination, kinship analysis and biogeographic origin prediction in Dongxiang group, which could be used as a powerful tool for case investigation.

The Belt and Road Initiative, Public Health Expenditure and Economic Growth: Evidence from Quasi-Natural Experiments
The United Nations 2030 Sustainable Development Goals (SDGs) involve society, economy, and environment, and the Belt and Road Initiative (BRI) is an important path to implement the SDGs. Moreover, the BRI is a vision for economic development of countries along the route. Although many studies documented the effect of the BRI on environment and economic performance, few studies have discussed the effect of the BRI on social and economic benefits. Therefore, we introduce the public health expenditure to explore the relationship between the BRI and the public health and economic growth of countries along the route from the dual perspective of social development and economic growth. Based on a panel data from 171 countries from 2010 to 2018, the current research explores whether the BRI can boost public health and promote economic growth in the belt-road countries. As a result, we found that the BRI boosted the expenditure of public health and effectively spurred economic growth in the belt-road countries. Furthermore, the effect of the BRI on the economic growth in the countries along the route depends on the level of public health expenditure in each country; the positive effect of the BRI on economic growth is significant when the public health expenditure level is moderate instead of low or high. The findings provide theoretical and practical insights into the SDGs of the BRI.

Trends in research related to menopausal hormone therapy from 2000 to 2021: A bibliometric analysis
We conducted the present bibliometric analysis to explore menopausal hormone therapy (MHT)-related research trends between 2000 and 2021. The Web of Science database was systematically searched from 2000 to 2021 to retrieve MHT-related publications. Visualization mapping and keyword cluster graphs were utilized to illustrate the research topics and hotpots. We included 11,616 MHT-related publications for this bibliometric analysis. The results showed that (1) MHT-related research had a very slow increase in the past 22 years, and the trend fluctuated. Sum of times cited and average citations per item had the same trend: a sharp decline from 2002 to 2003, and a rapid increase from 2003 to 2006, reaching the peak in 2006, then following a downward trend. The average H-index was 57, peaking in 2001; (2) the USA, the League of European Research Universities, and Dr. JoAann Manson from Harvard University contributed the most; (3) Menopause: The Journal of The North American Menopause Society had the most significant number of MHT-related publications; (4) the research hotpots primarily focused on MHT for treating menopausal symptoms and the impact of MHT on women's health. According to previous studies, MHT was the most effective treatment for managing vasomotor symptoms of menopause, but results from the clinical trials and observational studies regarding MHT adverse events remain inconsistent. Mechanisms are fundamental when clinical studies give conflicting results. Therefore, future studies should focus on adverse events and their mechanisms.

PROTOCOL: The effectiveness, implementation and cost effectiveness of mentoring programmes in reducing anti-social, violent and offending behaviour in children aged 17 years and below: A mixed method systematic review
This is the protocol for a Campbell systematic review. The review will address the following research questions: What is the evidence on the effects of adult mentoring programmes in reducing anti-social, violent and offending behaviour in children aged under 18 years? Are these effects sustained after the end of mentoring? Which aspects/features of adult mentoring programmes promote the reduction of anti-social, violent and criminal behaviour in children aged under 18 years? What are the hindering factors/barriers that affect the successful implementation of adult mentoring programmes in children aged under 18 years? What are the supporting factors/facilitators that contribute to the successful implementation of adult mentoring programmes in children aged under 18 years? What is the evidence on programme costs and incremental cost effectiveness? (The incremental (or marginal cost) is the cost of providing the intervention over and above the cost of usual services).

The efficacy and safety of intermittent preventive treatment with sulphadoxine-pyrimethamine vs artemisinin-based drugs for malaria: a systematic review and meta-analysis
Background Malaria is one of the most serious global problems. The objective of this study is to assess whether intermittent preventive treatment (IPT) using artemisinin-based combination therapies (ACTs) was a promising alternative to IPT with sulphadoxine-pyrimethamine (IPT-SP). Methods We searched the following sources up to 12 August 2020: PubMed, The Cochrane Library, Embase, Web of Science, CNKI, CBM, VIP and WanFang Database from inception. The randomized controlled trials comparing SP with ACTs for malaria were included. Data were pooled using Stata.14 software. We performed subgroup analysis based on the different types of ACTs groups and participants. Results A total of 13 studies comprising 5180 people were included. The meta-analysis showed that ACTs had the lower risk of number of any parasitemia (RR=0.46; 95% CI 0.22 to 0.96, p=0.039; I-2=90.50%, p<0.001), early treatment failure (RR=0.17; 95% CI 0.06 to 0.48, pI(2)=66.60%, p=0.011) and late treatment failure (RR=0.34; 95% CI 0.13 to 0.92, pI(2)=87.80%, p<0.001) compared with SP. There was no significant difference in adequate clinical response, average hemoglobin and adverse neonatal outcomes. Conclusion Combinations with ACTs appear promising as suitable alternatives for IPT-SP.

Evidence Based Social Science in China Paper 4 : The quality of social science systematic reviews and meta-analysis published from 2000-2019
Objectives: To examine the characteristics, methodological and reporting quality of systematic reviews and meta-analyses in social science journals in China. Study Design and Setting: The Chinese Social Sciences Citation Index (CSSCI) databases were searched for systematic reviews and meta-analysis published between January 2000 and December 2019. We randomly selected 200 articles from the 401 identified in our search. The Assessing the Methodological Quality of Systematic Reviews (AMSTAR) and the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) checklists were used to assess the methodological and reporting quality, respectively. Results: The 200 articles we selected covered a wide range of research fields in 9 disciplines, most of which belonged to management, education and psychology. The mean AMSTAR score and PRISMA score was 8.99 +/- 3.36 points and 14.74 +/- 3.96 points, respectively. These findings indicated that the quality of the systematic reviews was below the average level. Meanwhile, year of publication was related to both methodological quality (P = 0.001) and reporting quality (P < 0.01). Conclusion: Although many systematic reviews and meta-analysis have been published in top Chinese journals, the methodological and reporting quality is troubling. Thus, the most urgent task is to increase the standard of systematic reviews and meta-analysis of every discipline rather than continuing to publish them in great quantity. (C) 2021 Elsevier Inc.
