Clinical trials
Mark has been involved with a plethora of trials of various designs in a broad range of fields. He makes significant contributions to funding applications, trial design, analysis, presentation and interpretation. To date, he has published on 39 randomised trials (protocol and/or results paper). He is involved with methodological research into cluster randomised trials as well as sample size calculations.
-
Meta-analysis
Mark has been involved with a variety of meta-analyses. He has found a novel way to interpret the heterogeneity parameter, tau, in random-effects meta-analysis of ratios. That said, he advocates for the reporting of tau, or exp(tau) for ratios, rather than tau^2 as it is most easily understood.
