Abstract：Original study reports on time-to-event (TTE) outcomes generally focus on median time to event and hazard ratio. In this paper, we introduce an approach of recreating individual patient data (IPD) for TTE outcomes, based upon digitized Kaplan-Meier curve, number of subjects at risk at given time points and total number of events occurred during the entire follow-up, utilizing the statistical software R as the analysis environment.
