In this book, I investigate statistical issues and develop methodological recommendations for individual patient data meta-analysis of prognostic factor studies projects. I undertook an empirical study to compare between the individual patient data (IPD)and aggregated data approach to assess PFs in breast cancer. I showed that the IPD approach is preferable over aggregated data. I developed eleven IPD meta-analysis models to investigate whether accounting for clustering of patients within studies should be undertaken and which approach is the best to use. The models differed by using either a…mehr

In this book, I investigate statistical issues and develop methodological recommendations for individual patient data meta-analysis of prognostic factor studies projects. I undertook an empirical study to compare between the individual patient data (IPD)and aggregated data approach to assess PFs in breast cancer. I showed that the IPD approach is preferable over aggregated data. I developed eleven IPD meta-analysis models to investigate whether accounting for clustering of patients within studies should be undertaken and which approach is the best to use. The models differed by using either a one-step or two-step approach, and whether they accounted for parameter correlation and residual variation. In addition, I developed three non-linear fractional polynomial IPD meta-analysis models based on whether one-step or two-step approach and whether first or second order fractional polynomial functions are performed.
