Summary receiver operating characteristic curves of MRI and CT for DNS diagnosis. (A) MRI; (B) CT. The curve is the regression line that summarized the overall prognostic accuracy. The upper and lower curves represent confidence intervals. Circles indicate individual study estimates of sensitivity and 1-specificity. The size of each circles is proportional to the sample size of individual study. SROC summary receiver operating characteristic, AUC area under the ROC curve, DOR diagnostic odd ratios.
