| HR (95% CI) | P | HR (95% CI) | P | |
| Multivariate Cox model: Treatment at 90 d | 0.80 (0.81 to 0.96) | 0.004 | 1.32 (1.26 to 1.38) | <0.001 |
| Multivariate Cox model: Treatment modality as time-varying factor | 0.82 (0.75 to 0.81) | <0.001 | 1.29 (1.23 to 1.35) | <0.001 |
| Propensity score: Matched cohort | 0.99 (0.89 to 1.10) | 0.800 | 1.35 (1.27 to 1.42) | <0.001 |
| Weighted multivariate Cox model: inverse probability of treatment weight | 0.93 (0.83 to 1.03) | 0.180 | 1.31 (1.24 to 1.38) | <0.001 |
