Standard deviation	0.05	0.05	0.15	0.05	0.08

The performance of models to predict ADRs induced by drug-drug interactions (DDIs) were estimated from 10-fold cross-validation. The values were calculated by using a DDI score threshold of 0.0 for all ADRs. The calculated positive predictive values (PPV) are given for the developed ADR models
