Area under the curve ‐optimized synthesis of prediction models from a meta‐analytical perspective
This study introduces a new method for synthesizing the summary results of binary prediction models reported in the prior studies using a linear predictor under a distributional assumption between the current and prior studies. The method provides an integrated predictor combining all predictors reported in the prior studies with weights. The vector of the weights is designed to achieve the hypothetical improvement of area under the receiver operating characteristic curve (AUC) on the current available data under a practical situation where there are different sets of covariates in the prior studies. We observe a counterin...

Commercial funding and estimated intervention effects in randomized clinical trials: systematic review of meta ‐epidemiological studies
In conclusion, we found no statistically significant association between commercial funding and estimated intervention effects when combining studies of commercial funding per se and studies of risk of commercial funder influence. A preplanned subgroup analysis indicated that trials with high risk of commercial funder influence exaggerated intervention effects by 12% (21% to 3%), on average. Our results differ from previous theoretical considerations and findings from methodological studies and therefore call for confirmation. We suggest it is prudent to interpret results from commercially funded trials with caution, espec...

Network Meta ‐Interpolation: Effect modification adjustment in network meta‐analysis using subgroup analyses
ConclusionsNMI ’s dominance in terms of estimation accuracy and CrI coverage appeared to be consistent across all scenarios. NMI represents an effective option for NMA in the presence of study imbalance and available subgroup data.This article is protected by copyright. All rights reserved.

Missingness mechanism messiness in meta ‐analysis: A response to “The importance of plausible data‐generating mechanisms in simulation studies”
We describe and justify our assumed scenario in meta-regression that we investigated. We also revisit the performance of the deletion method and how it is tied into the assumed missingness model. Lastly, we reiterate the importance of conducting sensitivity analyses assessing different ways of handling missing data given different assumptions and offer this study as a starting point for future research.
