OBJECTIVE Two investigations evaluate Bayesian meta-regression for detecting treatment interactions. STUDY DESIGN AND SETTING The first compares analyses of aggregate and individual patient data on 1,860 subjects from 11 trials testing angiotensin converting enzyme (ACE) inhibitors for nondiabetic kidney disease. The second explores meta-regression for detecting treatment interaction on 671 c...

conclusions the results of this research have important implications regarding the attention of students’ counselors to meta-cognitive dimensions in order to prevent students’ tendency for addiction. results the rate of students’ addiction potential tendency can be predicted by having characteristics of their meta-cognition. it also appeared that among the five parameters of meta-cognition, the...

BACKGROUND The pragmatic-explanatory continuum indicator summary version 2 (PRECIS-2) tool has recently been developed to classify randomized clinical trials (RCTs) as pragmatic or explanatory based on their design characteristics. Given that treatment effects in explanatory trials may be greater than those obtained in pragmatic trials, conventional meta-analytic approaches may not accurately a...

This work investigates the effectiveness of using computer-based machine learning regression algorithms and meta-regression methods to predict performance data for Australian football players based on parameters collected during daily physiological tests. Three experiments are described. The first uses all available data with a variety of regression techniques. The second uses a subset of featu...

the objective of this study was to evaluate the effect of frequency of feeding total mixed ration (tmr) on total-tract digestibility, milk production and composition in lactating cows, using meta-analysis and meta-regression approaches. data of fourteen experiments having containing 25 comparisons between treatment (higher feeding frequency) and control (lower feeding frequency) groups, defined...

Meta-regression models are commonly used to synthesize and compare effect sizes. Unfortunately, traditional meta-regression methods are ill-equipped to handle the complex and often unknown correlations among non-independent effect sizes. Robust variance estimation (RVE) is a recently proposed meta-analytic method for dealing with dependent effect sizes. The robumeta package provides functions f...
