Table 1. We compare the time-to-first event (HR) studies with the win ratio.
| Hazard Ratio | Win Ratio |
|---|---|
| Simple, reproducible. | Less experience, lack of familiarity. |
| Requires proportional hazards. | Does not require proportional hazards (uses pairs of comparisons). |
| Ignores occurrence of fatal events after non-fatal events. | Incorporates all fatal events of interest. |
| Does not consider the hierarchy of events. | Allows establishing a hierarchy of events and analyzing other patient-focused outcomes. |
| Estimates sample size and statistical power. | No estimate of sample size and statistical power. |
| Distinguishes between short-term and long-term events. | With a single “metric” it combines short- and long-term efficacy. |
