Data are expressed as Spearman’s r coefficient and related 95% CI.

PU perfusion unit, 95% CI 95% confidence interval, HA: hyperemic area, LD: laser doppler.

Delta flow = peak flow − resting flow.

Hyperemic area index = hyperemic area/resting flow.

Ethnicity: Caucasic > North African > Moroccan.
