Fig. 3From: A practical solution to estimate the sample size required for clinical prediction models generated from observational research on dataHow the follow-up/timepoint ratio affects the sample size. Analysis of the variation in sample size for the time-to-event models relative to the ratio between the expected average follow-up of the dataset and the time points of interest for the predictions.
