Estimated and reported milestone survival probabilities using the treatment effect calculator (Supplementary File S1) assuming an exponential survival distribution in adjuvant therapy trials. DFS = disease-free survival, HR = hazard ratio.
Type of Adjuvant Therapy | Milestone Time (Months) | Reported Milestone DFS Probability in Control Group | Estimated HR and CIs for DFS | Estimated Milestone DFS Probability in Treatment Group | Reported Milestone DFS Probability in Treatment Group | Difference between Estimated Versus Reported Milestone DFS Probability | Reference |
