Figure 3: Model selection and validation.

Figure 3:

Accuracy (A) and Cohen’s Kappa (B) were calculated for each model during repeated cross-fold validation. Sensitivity (C) and specificity (D) for all four intrinsic SSc subsets are plotted from repeated cross-fold validation for the final model. In external validations, concordance of intrinsic subset assignment between the original publications and our analysis is plotted in black and Cohen’s Kappa in blue (E). Balanced accuracy (concordance) is shown for each of the intrinsic subsets represented in each dataset (F).
