ROC curves based on logistic regression analysis of cut-off values for the mean glucocorticoid dose. A. ROC curve for APOs (P = 0.01). The AUC was 0.674 and the cut-off value for the mean prednisone dose was 6.5 mg/day. B. ROC curve for PB (P < 0.01). The AUC was 0.808 and the cut-off value for the mean prednisone dose was 10.0 mg/day. C. ROC curve for LBW (P = 0.06). The AUC was 0.662 and the cut-off value for the mean prednisone dose was 6.5 mg/day. D. ROC curve for LFD (P = 0.18). The AUC was 0.615 and the cut-off value for the mean prednisone dose was 6.7 mg/day. ROC: receiver operating characteristic; AUC: area under the curve; TPF: true positive fraction; FPF: false positive fraction; APOs: adverse pregnancy outcomes; PB: preterm birth; LBW: low birth weight; LFD: light-for-date
