Figure 4. 4S is highly correlated with modified Rodnan skin score (mRSS) across all datasets.

Figure 4

Correlation plots comparing mRSS with the systemic sclerosis skin severity score (4S) for all of the datasets. Panels A and B (n = 54 and 72, respectively) are discovery cohorts and panels C–G (n = 66, 161, 13, 29, and 22, respectively) are validation cohorts. Each data point represents a patient skin biopsy. The blue line is the line of best fit and the gray region represents its 95% CI. HSS, Hospital for Special Surgery.
