Figure 3. — Pain pressure means (mmHg) corresponding to subjectively calibrated P10 (10-mm VAS) and P50 (50-mm VAS) represented by group (FM, HC) and TSPO polymorphism (HAB, MLAB). Error bars represent the lower and the upper 95% confidence intervals. Squares represent the mean of the data. P10, individually calibrated pain pressure matching a subjective pain rating of 10/100-mm visual analogue scale (VAS); P50, individually calibrated pain pressure matching a subjective pain rating of 50/100-mm VAS; FM, fibromyalgia; HC, healthy controls; HAB, high affinity binders; MLAB, mixed/low affinity binders; TSPO, translocator protein; VAS, visual analogue scale; FM MLAB = 30, FM HAB = 48, HC MLAB = 17, HC HAB = 21.
