Table 4.

Exploratory cox proportional hazards models of the association between 12-week ΔMET ≥ 0.5 and ≥1.5 and survival among CR completers with cancer, adjusting for relevant covariates (N = 330)^†.

ΔMET ≥ 0.5	HR (95% CI)
Model 1	0.83 (0.50–1.40)
Model 2	0.90 (0.53–1.52)
Model 3	0.91 (0.54–1.54)
ΔMET ≥ 1.5	HR (95% CI)
Model 1	0.57 (0.24–1.31)
Model 2	0.55 (0.24–1.28)
Model 3	0.41* (0.17–0.99)

Note.

^†Sample size of CR-completers was reduced to 330 owing to 15 participants who were missing BMI data and 16 participants who were missing systolic and/or diastolic blood pressure data. CR = cardiac rehabilitation; MET = peak metabolic equivalent; CVD = cardiovascular disease. Model 1 represents the unadjusted model. Model 2 was minimally adjusted (age, sex, and body mass index) and Model 3 fully adjusted (comorbid type II diabetes; co-morbid chronic obstructive pulmonary disease; baseline diastolic and systolic BP; current or former smoking status).
