Note—95 % confidence intervals included in parentheses. TP, TN, FP and FN presented as counts. Accuracy, sensitivity and specificity present as percentages.
TP = True positive, TN = true negative, FP = false positive, FN = false negative, AUC = area under the receiver operating characteristic curve.
