  1. Data are expressed as Spearman’s r coefficient and related 95% CI.
  2. PU perfusion unit, 95% CI 95% confidence interval, HA: hyperemic area, LD: laser doppler.
  3. Delta flow = peak flow − resting flow.
  4. Hyperemic area index = hyperemic area/resting flow.
  5. Ethnicity: Caucasic > North African > Moroccan.
  6. *p < 0.05.
  7. **p < 0.001.
