External validation of VAMPr prediction model.

The external dataset includes 13 Enterobacter cloacae, 31 Escherichia coli, 24 Klebsiella pneumoniae and 21 Pseudomonas aeruginosa isolates. All isolates were tested against 3 antibiotics (cefepime, ceftazidime and meropenem). We reported the accuracy as the fraction of correct predictions, and the AUROC (area under the receiver operator curve) represents the area under the operator-receiver characteristic. The AUROC value is n/a for E. cloacae as all 13 isolates are susceptible to meropenem.
