Shear-wave velocity values (metres per second), measured by shear-wave elastography, at the Rodnan skin sites, at baseline and follow-up, in SSc and controls. Percentage change values are presented as median (Q1–Q3). Patients 2 and 3 progressed from oedematous to atrophic phase. Red dotted lines represent oedematous patients at baseline, and the grey lines represent patients in fibrotic phase at baseline
