Estimated hazard ratios (95% CI) for all-cause mortality based on supervised exercise dose (MET-h per week) in independent Cox models for two time periods
| Model | Event time <9 years | Event time >9 years | ||||
| HR* | 95% CI | P Value | HR | 95% CI | P Value | |
| Unadjusted | 0.85 | 0.53 to 1.36 | 0.492 | 0.57 | 0.35 to 0.92 | 0.023 |
| Multivariate Model 1 | 1.67 | 1.00 to 2.88 | 0.049 | 1.02 | 0.60 to 1.73 | 0.939 |
| Multivariate Model 2 (propensity score) | 1.32 | 0.76 to 2.30 | 0.322 | 0.98 | 0.56 to 1.72 | 0.949 |
*HR for exercise volume >6.6 MET-h per week (≤6.6. MET-h per week is reference category) Time partitioning at 9 years corresponds to a distinct change in the slope of the hazard.
