3. Fig. 2
Scatterplots showing individual thermotactile perception thresholds for warmth and cold versus skin thickness together with linear curve fit data. Red color: White-collar workers not exposed to vibration (NEV); Blue color: Blue-collar workers exposed to vibration and heavy manual work (EV); Black color: All subjects together.
