Fig. 2From: Subclinical dermal involvement is detectable by high frequency ultrasound even in patients with limited cutaneous systemic sclerosisDermal thickness evaluated by skin high-frequency ultrasound (US) in patients with systemic sclerosis (SSc) and healthy control subjects (CNT) (SSc vs CNT: p < 0.0001 for all, with the exclusion of thigh). Data are presented as box plots for different skin areas, with the 5th, 10th, 50th (median), 90th, 95th percentilesBack to article page
