Fig. 2

Ultrasound-measured skin thickness and stiffness stratified by disease subtype and modified Rodnan skin score. In box and whisker plots (a, b), lines from the bottom to the top indicated the minimum, 25th percentile, median, 75th percentile, and maximum values; dots indicated outliers, and crosses indicated mean values. In scatter plots (c, d), a single dot denoted a single measurement, and the dashes denoted the mean values. Kruskal-Wallis test with Dunn’s correction for multiple comparisons was conducted. Outliers were identified by the Turkey method. ***p < 0.001, **p < 0.01, *p < 0.05
