Mean change and 95% confidence intervals from linear mixed-effect model of clinical outcomes from pre-treatment to 12-weeks of intervention for c-AEP (n = 50). c-AEP, combined aerobic exercise protocol; DBP, diastolic blood pressure; HR, heart rate; HF norm, high frequency power in normalized units; LF norm, low frequency power in normalized units; LF/HF ratio, low frequency to high frequency ratio; pNN50, percent of RR intervals differing by more than 50 ms; RMSSD, root mean squared of successive RR interval differences; SBP, systolic blood pressure; SDNN, standard deviation of RR intervals. † Average of two manual brachial blood pressures.
