Baseline HR (bpm) 73.16 ± 8.23 71.89 ± 8.10 74.31 ± 8.28 0.208
Pre-exercise     
Baseline diameter (mm) 3.32 ± 0.42 3.56 ± 0.37 3.11 ± 0.36 <0.001
FMD (%) 8.98 ± 4.69 7.44 ± 3.41 10.36 ± 5.26 0.007

FMD (%) 7.51 ± 4.03 7.39 ± 4.42 7.62 ± 3.71 0.807
ΔFMD (%)† −1.47 ± 4.54 −0.05 ± 3.04 −2.75 ± 5.28 0.008
Treadmill exercise     
Exercise duration (sec)* 665 (613 – 747) 735 (658 – 823) 620 (600 – 700) <0.001
METS* 13.3 (12.1 – 14.3) 13.7 (13.1 – 15.8) 12.4 (11.7 – 13.4) 0.001
Maximum HR (%)‡ 90.23 ± 1.96 90.07 ± 1.80 90.41 ± 2.12 0.377
  1. Values are mean ± SD, median with IQR (25th – 75th percentiles), or absolute number (%).
  2. * Logarithmic transformation was done for these variables due to skewed distribution.
  3. † ΔFMD = post-exercise FMD (%) – pre-exercise FMD (%).
  4. ‡ Maximum HR (%) = percentage of age-predicted maximum heart rate.
  5. BPM = beat per minute; DBP = diastolic blood pressure; HR = heart rate; IQR = interquartile range; METS = metabolic equivalents; SBP = systolic blood pressure.
