The Number Needed to Treat (NNT) for Survival Endpoint
Description
Estimate the NNT using the proposed method in Yang and Yin's paper (2019)
, in which the NNT-RMST (number needed to
treat based on the restricted mean survival time) is defined as the RMST (restricted
mean survival time) in the control group divided by the difference in RMSTs
between the treatment and control groups up to a chosen time t.
