IIEF-5 score explained variance. Explained variance from unadjusted models (R2Unadjusted model) including only individual variable (e.g. age) or groups of variables (e.g. lifestyle) of interest. Explained variance due to each group over and above all other covariates determined as the difference between the R2 from the full model including all covariates and a reduced model with the group or variable of interest removed: ΔR2 = R2Full model – R2Reduced model.
