| ECP | n | HR (95%CI)b | p | HR (95%CI)c | p | Number of heart failures | Number of heart failures/1000 person-years |
|---|---|---|---|---|---|---|---|
| Q1 | 588 | 2.37 (1.68–3.35) | <0.0001 | 1.96 (1.38–2.78) | <0.001 | 107 | 9.9 |

| Q4a | 588 | 1.00 | 1.00 | 51 | 3.6 |
Note: Q1: ECP < 49.84 mL/mmHg; Q2: ECP = 9.84–11.64 mL/mmHg; Q3: ECP = 11.65–13.92 mL/mmHg; Q4: ECP >13.92 mL/mmHg.
Abbreviations: 95%CI = 95%confidence interval; ECP = exercise cardiac power; HDL = high-density lipoprotein; HR = hazards ratio; LDL = low-density lipoprotein; Q = quartile.
a
Q4 is treated as reference.
b
Adjusted for age and examination year.
c
