Table 3 Results of stepwise regression modelling on exercise‐induced change in left ventricular mass (final model shown, including only significant predictors of left ventricular mass).

SBP, systolic blood pressure.

Predictors with p<0.05 are presented.

Note that the overall R² for the model containing all variables is 6.5%.

*The incremental R² shows the additional variability in exercise‐induced change in left ventricular mass explained by adding the variable to a model that contains all other variables listed.

†Required log transformation to normalise distribution.

‡The β‐coefficient is for a 1 SD increase in continuous variables (on the transformed scale where specified).
