Trade-off involved in choosing between methods when extending the follow-up period of a survival trial.
<p>Methods considered: (A), data is combined assuming independent stage-wise increments; (B), patient-wise separation with pre-fixed end of first-stage follow-up; (C), naive patient-wise separation without pre-fixed end of first-stage follow-up; and (D), patient-wise separation using the full-data guaranteed level-<i>Ξ±</i> test.</p

Development of a CONSORT Extension for adaptive clinical trials
<p>The ACE Project aims to develop a consensus-driven reporting guidance tailored for ADs in the form of a CONSORT extension. We hope this will enhance transparency, credibility, reproducibility, and replicability of adaptive trials. The hope would be to facilitate uptake of ADs in clinical trials research when appropriate.</p><p>The ACE Project is jointly funded by the NIHR and MRC HTMR, and is led by a multidisciplinary Steering Working Group of international experts in collaboration with the CONSORT Executive Group and the MRC HTMR Adaptive Designs Working Group</p
