 Comparisons between patients with CAD and healthy controls on incremental shuttle walk test (ISWT) indices

Overall CAD (n = 53)Controls (n = 19)Intergroup p value*Group × exercise effects†
F(1, 70)p Value
Data are mean (SD) or median (interquartile range).
*Unpaired Student’s t or Mann-Whitney U test; †two way analysis of variance with repeated measures of the exercise effect in group by exercise interactions.
Δ indicates changes after ISWT; DBP, diastolic blood pressure; HR, heart rate; RPE, rate of perceive exertion; SBP, systolic blood pressure.
