Exercise ECG data for the four exercise tests

Placebo 1Placebo 2Drug 1Drug 2p Value
Values are mean (SD).
Comparisons between all four exercise tests using two way parametric analysis of variance; pairwise comparisons using Student's t test for paired data with Bonferroni correction.
*p<0.05 v placebo 1; †p<0.05 v drug 1.
RPP, rate–pressure product; SBP, systolic blood pressure.
