Utilization of the evidence from studies with no events in meta-analyses of adverse events: an empirical investigation
(
Springer
, 2021 , Article)
Zero-events studies frequently occur in systematic reviews of adverse events, which consist of an important source of evidence. We aimed to examine how evidence of zero-events studies was utilized in the meta-analyses of ...
Arcsine-based transformations for meta-analysis of proportions: Pros, cons, and alternatives
(
Wiley Open Access
, 2020 , Article)
© 2020 The Authors. Health Science Reports published by Wiley Periodicals LLC. Meta-analyses have been increasingly used to synthesize proportions (eg, disease prevalence) from multiple studies in recent years. Arcsine-based ...
Laplace approximation, penalized quasi-likelihood, and adaptive Gauss-Hermite quadrature for generalized linear mixed models: Towards meta-analysis of binary outcome with sparse data
(
BMC
, 2020 , Article)
© 2020 The Author(s). Background: In meta-analyses of a binary outcome, double zero events in some studies cause a critical methodology problem. The generalized linear mixed model (GLMM) has been proposed as a valid ...
Double-zero-event studies matter: A re-evaluation of physical distancing, face masks, and eye protection for preventing person-to-person transmission of COVID-19 and its policy impact
(
Elsevier
, 2021 , Other)
In a recent timely systematic review, Chu et al. [1] assessed the effectiveness of face masks, eye protection, and physical distancing for preventing COVID-19. Because the sample sizes are not large, especially in some ...
Data extraction error in pharmaceutical versus non-pharmaceutical interventions for evidence synthesis: Study protocol for a crossover trial
(
Elsevier
, 2023 , Article)
BackgroundData extraction is the foundation for research synthesis evidence, while data extraction errors frequently occur in the literature. An interesting phenomenon was observed that data extraction error tend to be ...
The odds ratio is “portable” but not the relative risk: Time to do away with the log link in binomial regression
(
Elsevier
, 2021 , Article)
Objectives: In a recent paper we suggest that the relative risk (RR) be replaced with the odds ratio (OR) as the effect measure of choice in clinical epidemiology. In response, Chu, and colleagues raise several points that ...
Many meta-analyses of rare events in the Cochrane Database of Systematic Reviews were underpowered
(
Elsevier
, 2021 , Article)
Background and ObjectiveMeta-analysis is a statistical method with the ability to increase the power for statistical inference, while it may still face the problem of being underpowered. In this study, we investigated the ...
Protocols for meta-analysis of intervention safety seldom specified methods to deal with rare events
(
Elsevier
, 2020 , Article Review)
ObjectivesMeta-analyses of rare events often generate unstable results, and selective reporting of the results may mislead the health care decision. Developing a synthesis plan for rare events in protocol may help to ...
Rapid evidence synthesis approach for limits on the search date: how rapid could it be?
(
John Wiley and Sons
, 2021 , Article)
Rapid reviews have been widely employed to support timely decision-making, and limiting the search date is the most popular approach in published rapid reviews. We assessed the accuracy and workload of search date limits ...
Methodological quality for systematic reviews of adverse events with surgical interventions: a cross-sectional survey.
(
BMC
, 2021 , Article)
An increasing number of systematic reviews assessed the safety of surgical interventions over time. How well these systematic reviews were designed and conducted determines the reliability of evidence. In this study, we ...
