Table 3 Paired delta change and comparing the magnitude of change between non-obese and obese patients at the end of the program

From: Effect of a phase 2 cardiac rehabilitation program on obese and non-obese patients with stable coronary artery disease

Variable Paired delta change for non-obese patients (n = 58) Paired delta change for non-obese patients, p value Paired delta change for obese patients (n = 62) Paired delta change for obese patients, p value Comparing the magnitude of change between non-obese and obese patients, p value
