Covariate adjustment in randomised trials: canonical link functions protect against model mis-specification
Ian R. White, Tim P Morris, Elizabeth Williamson
Covariate adjustment has the potential to increase power in the analysis of randomised trials, but mis-specification of the adjustment model could cause error. We explore what erro…
Introducing the treatment hierarchy question in network meta-analysis
Georgia Salanti, Adriani Nikolakopoulou, Orestis Efthimou +3
Background: Comparative effectiveness research using network meta-analysis can present a hierarchy of competing treatments, from the least to most preferable option. However, the r…
Handling an uncertain control group event risk in non-inferiority trials: non-inferiority frontiers and the power-stabilising transformation
Matteo Quartagno, A. Sarah Walker, Abdel G. Babiker +4
Background. Non-inferiority (NI) trials are increasingly used to evaluate new treatments expected to have secondary advantages over standard of care, but similar efficacy on the pr…
A matrix-based method of moments for fitting multivariate network meta-analysis models with multiple outcomes and random inconsistency effects
Dan Jackson, Sylwia Bujkiewicz, Martin Law +2
Random-effects meta-analyses are very commonly used in medical statistics. Recent methodological developments include multivariate (multiple outcomes) and network (multiple treatme…
