Appendix Figure 1. Graphical presentation of between-group difference metrics.

Appendix Figure 1

(A) the hazard ratio, (B) the relative time, and (C) various model-free, between-group difference measures for a new treatment (solid curve) and a control (dotted curve); the slopes of the lines in A and B are the hazard ratio and the relative time, respectively, the distance between the two closed circles (horizontal line) in C is the difference for two medians; and the distance between the two closed squares in C (vertical line) is the difference of two event rates at 36-months; the shaded area in C is the difference in the restricted mean survival time up to 48 months
