Model performance by therapy line.

Summary of area under the receiving operating characteristic curve (AUC) values for RF trained with selected input variable sets, calculated over ten multiple runs of 10-fold cross-validation (8-weeks and 24-weeks outcome), by stratifying for therapy line. *p<0.05 with respect to the best model. GRT = genotype resistance test. TH = treatment history. cART = combination antiretroviral therapy.
