Individualized treatment rules leverage patient-level information to tailor treatments for individuals. Estimating these rules, with the goal of optimizing expected patient outcomes, typically relies on individual-level data to identify the variability in treatment effects across patient subgroups defined by different…

In psychology, the use of portable technology and wearable devices to ease participant burden in data collection is on the rise. This creates increased interest in collecting real-time or near real-time data from individuals within their natural environments. As a result, vast amounts of observational time series data…

OBJECTIVES: The aim of the study was to assess the feasibility of living network meta-analysis (NMA) taking into account the pace of evidence generation across different medical areas. STUDY DESIGN AND SETTING: We performed a systematic review to identify published NMAs. For each NMA, we calculated the cumulative numb…

Any experiment brings about results and conclusions that necessarily have a component of uncertainty. Many factors influence the degree of this uncertainty, yet they can be overlooked when drawing conclusions from a body of research. Here, we showcase how subjective logic could be employed as a complementary tool to me…

AIM: To assess robustness of findings in recent systematic reviews of atypical antipsychotics in schizophrenia patients in the presence of heterogeneity. METHODS: Relative efficacy was measured in seven direct comparisons of mean difference (MD) in average positive and negative syndrome scale total score and compariso…

This paper proposes the use of the tools of statistical meta-analysis as a method of conflict resolution with respect to experiments in cognitive linguistics. With the help of statistical meta-analysis, the effect size of similar experiments can be compared, a well-founded and robust synthesis of the experimental data…

The amount of available biomedical information is vast and growing. Natural limitations of the way clinicians and researchers approach this treasure trove of information comprise difficulties locating the information, and once located, cognitive biases may lead to inappropriate use of the information. Systematic review…

Meta-analysis is a powerful tool for combining related studies but such an aggregation would be flawed if studies investigated different populations or applied different methods in this investigation. While studies with differences that are statistically detected but not explained can be analysed by techniques of rando…

We congratulate the authors for the new meta-analysis model that accounts for different outcomes. We discuss the modeling choice and the Bayesian setting, specifically, we point out the connection between the Bayesian hierarchical model and a mixed-effect model formulation to subsequently discuss possible future method…

The meta-analysis of coefficient alpha across many studies is becoming more common in psychology by a methodology labeled reliability generalization. Existing reliability generalization studies have not used the sampling distribution of coefficient alpha for precision weighting and other common meta-analytic procedures…

Intervention studies represent webs of interrelated substantive and methodological characteristics that take on different patterns in different studies and different intervention areas. All too often, meta-analysts do not give close attention to the possibility that these interrelated differences among studies are rela…

The term meta-analysis refers to the quantitative combination of data from independent trials. Where the result of such combination is a descriptive summary of the weight of the available evidence, the exercise is of undoubted value. Attempts to apply inferential methods, however, are subject to considerable methodolog…

RATIONALE: Meta-analysis, a powerful technique for combining effect estimates from multiple studies, enhances statistical power and precision. However, its adoption can be hindered by challenges in statistical interpretation and the complexity of specialized software. MetaXL, a freely available Microsoft Excel add-in,…
