Comparison of HRs for all-cause mortality between low, moderate and higher sCRF participants at CR entry (n=670)

All-cause mortality (n=206 deaths) Low sCRF* (referent) (n=128) Moderate sCRF HR (95% CI) (n=317) p Value Higher sCRF† HR (95% CI) (n=225) p Value
Model 1: unadjusted 1.00 0.50 (0.37 to 0.68) <0.0005 0.25 (0.17 to 0.37) <0.0005
Model 2: adjusted for age 1.00 0.55 (0.40 to 0.75) <0.0005 0.35 (0.23 to 0.53) <0.0005
Model 3: adjusted for covariates 1.00 0.59 (0.42 to 0.83) 0.002 0.40 (0.25 to 0.64) <0.0005

Model 3 covariates were as follows: age; ACE-inhibitor, statin, diuretic, antiplatelet therapy use; diabetes, other CVD, waist circumference, TC/HDL ratio, date of CR entry, marital status, physical inactivity, resting heart rate, exercise test mode and negative exercise test (ECG).

*Entry sCRF level <6 METs (men) and <5 METs (women) at CR entry.

†Entry sCRF level ≥8 METs (men) and ≥7 METs (women) at CR entry.

CVD, cardio vascular disease; CR, cardiac rehabilitation; METs, metabolic equivalents; TC/HDL, total cholesterol high-density lipoprotein ratio; sCRF, submaximal cardiorespiratory fitness.
