Comparison of the skin temperature measured during the CSTs and NFCI severity assessed clinically. The skin temperatures for the great toe and the mean of toes 2–5 for the REST and EX conditions are grouped according to the severity of NFCI clinically determined independently of the CST. Skin temperatures before immersion and that after 5 min of rewarming are given. The cold sensitivity grading resulting from these skin temperatures[14] are indicated by colours: normal = green, borderline = light green, mild = blue, mild-moderate = pink, moderate = yellow, moderate-severe = orange, severe = red.
