Biomechanical characteristics of skin in patients with WS and matched controls. Measurements are shown for retraction time (RT, panel A), lift pressure (dP, panel B), lift time (dT, panel C), viscoelasticity (VE, panel D), and Young’s modulus (E, panel E). WS participants are noted as circles and controls are squares. The mean (long line) and SD (shorter line) are also noted. P values are recorded above each comparison.
