ruppert_ipd: OS Curves from Ruppert (2020)
In PwePred: Event/Timeline Prediction Model Based on Piecewise Exponential
ruppert_ipd R Documentation
OS Curves from Ruppert (2020)
Description
OS Curves for IPI 4-5 (red curve) from Figure 2A in Ruppert (2020)
Usage
ruppert_ipd
data(ruppert_ipd, package="PwePred")
Format
Survival.time: time
Status: 1 for events, 0 for censoring
Note
We digitize the OS curves for IPI 4-5 (red curve) from Figure 2A in Ruppert (2020), using WebPlotDigitizer (Rohatgi A (2024)). Subsequently, we reconstruct individual subject data (IPD) using the IPDfromKM package (Liu (2021)).
