Table 3.
Independent predictors of a “Moderate” or an “Optimal” increase in VO2peak from baseline to the end of CR program (multivariable logistic regression analysis)
| Variable | “Moderate” improvement: final VO2peak Δ > +5% from baseline (R2 = 0.18) |
“Optimal” improvement: final VO2peak Δ ≥ +15% from baseline (R2 = 0.24) |
