Figure 1.

AUC-ROC of the final model to predict a response to prokinetics or neuromodulators with the predictors delayed GCSI, diabetes, infectious prodrome, and BMI using ridge regression. The AUC-ROC were 0.72 for neuromodulators or prokinetics (blue line), 0.64 for neuromodulators without prokinetics (red line), and 0.83 for prokinetics without neuromodulators (green line). AUC-ROC, area under the receiver operator characteristic curve; BMI, body mass index; GCSI, Gastroparesis Cardinal Symptom Index.
