Sensitivity and Subgroup Analyses
HEMORRHAGIC STROKE
Exercise was cost-effective for improving cognitive function, but not quality of life.

The sensitivity analysis using imputed data produced results consistent with the base case analysis, confirming that the exercise program, while costlier, was more effective than the balance and tone program. eTable 2, eTable 3, eTable 4 and the eAppendix in
