Individual participant data (IPD) from such trials can be obtained and combined in a so\u2010called IPD meta\u2010analysis (IPD\u2010MA), to summarize the overall intervention effect. We performed a narrative literature review to provide an overview of methods for conducting an IPD\u2010MA of randomized intervention studies with a time\u2010to\u2010event outcome. We focused on identifying good methodological practice for modeling frailty of trial participants across trials, modeling heterogeneity of intervention effects, choosing appropriate association measures, dealing with (trial differences in) censoring and follow\u2010up times, and addressing time\u2010varying intervention effects and effect modification (interactions).We discuss how to achieve this using parametric and semi\u2010parametric methods, and describe how to implement these in a one\u2010stage or two\u2010stage IPD\u2010MA framework. We recommend exploring heterogeneity of the effect(s) through interaction and non\u2010linear effects. Random effects should be applied to account for residual heterogeneity of the intervention effect. We provide further recommendations, many of which specific to IPD\u2010MA of time\u2010to\u2010event data from randomized trials examining an intervention effect.We illustrate several key methods in a real IPD\u2010MA, where IPD of 1225 participants from 5 randomized clinical trials were combined to compare the effects of Carbamazepine and Valproate on the incidence of epileptic seizures.<\/jats:p>","DOI":"10.1002\/jrsm.1384","type":"journal-article","created":{"date-parts":[[2019,11,23]],"date-time":"2019-11-23T22:03:10Z","timestamp":1574546590000},"page":"148-168","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":90,"title":["Individual
