Fig. 2From: Clinical predictors of response to methotrexate in patients with rheumatoid arthritis: a machine learning approach using clinical trial dataReceiver-operating characteristic (ROC) curves of algorithms validated on the test set for the “DAS28-ESR” model (N = 410). The area under the curve (AUC) for the least absolute shrinkage and selection operator (LASSO; dashed) and random forests (RF; solid) methods validated on the test set were 0.79 and 0.68, respectively.
