Over the last three quarters of a century, international guidelines and regulations have undergone significant changes in how children are problematised as participants in biomedical research. While early guidelines enacted children as vulnerable subjects with diminished autonomy and in need of special protection, beginning in the early 2000s,…

Many research institutions and funders have recently stated their commitment to actively support and promote 'Equality, Diversity and Inclusion' (EDI) in various aspects of health research including Patient and Public Involvement (PPI). However, translating this commitment into specific research projects presents significant challenges that…

Cochrane reviews are known to be a high-quality source of evidence synthesis supporting health care decisions. In a recently conducted study, we analyzed the trends in epidemiology and reporting of published systematic reviews over the last 20 years. This sample of 1132 systematic reviews included 84 Cochrane reviews. We have learned several…

N-of-1 trials, a special case of Single Case Experimental Designs (SCEDs), are prominent in clinical medical research and specifically psychiatry due to the growing significance of precision/personalized medicine. It is imperative that these clinical trials be conducted, and their data analyzed, using the highest standards to guard against threats…

Estimation of within-trial interactions in meta-analysis is crucial for reliable assessment of how treatment effects vary across participant subgroups. However, current methods have various limitations. Patients, clinicians and policy-makers need reliable estimates of treatment effects within specific covariate subgroups, on relative and absolute…

Population adjustment methods such as matching-adjusted indirect comparison (MAIC) are increasingly used to compare marginal treatment effects when there are cross-trial differences in effect modifiers and limited patient-level data. MAIC is based on propensity score weighting, which is sensitive to poor covariate overlap and cannot extrapolate…

Pathway-based differential expression analysis allows the incorporation of biological domain knowledge into transcriptomics analysis to enhance our understanding of disease mechanisms. To integrate information among multiple studies at the pathway level, pathway-based meta-analysis can be performed. Paired or partially paired samples are common in…

Mathematical modeling studies are increasingly recognised as an important tool for evidence synthesis and to inform clinical and public health decision-making, particularly when data from systematic reviews of primary studies do not adequately answer a research question. However, systematic reviewers and guideline developers may struggle with…

Workplace learning is fundamental in contextualizing theoretical concepts into practice, making it opportune for professionals to learn emerging concepts. With genomic testing transitioning from the research space into healthcare, there are more opportunities to engage with workplace learning related to genomic medicine. We therefore aimed to…

Synthesizing findings about the indirect (mediated) effect plays an important role in determining the mechanism through which variables affect one another. This simulation study compared six methods for synthesizing indirect effects: correlation-based MASEM, parameter-based MASEM, marginal likelihood synthesis, an adjustment to marginal likelihood…

Over the past decade, the development of three-dimensional mammalian cell organization--called human organoids--from stem cells has provided a framework for future clinical therapies. As human organoid research progresses, we also need to keep in mind the cross-cultural and ethical dimensions of human organoids research. Our review article aims to…

Background: Eighty-five percent of medical research goes to waste, partly because it is not appropriately communicated to stakeholders. This represents a critical issue for the research community, especially because individuals who are impacted by research should be able to readily access that research. Making research findings accessible to key…

Many randomized trials evaluate an intervention effect on time-to-event outcomes. Individual participant data (IPD) from such trials can be obtained and combined in a so-called IPD meta-analysis (IPD-MA), to summarize the overall intervention effect. We performed a narrative literature review to provide an overview of methods for conducting an…

Writing and genre scholarship has become increasingly attuned to how various nontextual features of written genres contribute to the kinds of social actions that the genres perform and to the activities that they mediate. Even though scholars have proposed different ways to account for nontextual features of genres, such attempts often remain…

The Hartung-Knapp method for random-effects meta-analysis, that was also independently proposed by Sidik and Jonkman, is becoming advocated for general use. This method has previously been justified by taking all estimated variances as known and using a different pivotal quantity to the more conventional one when making inferences about the…
