Receiver operating characteristic analysis. (A) The graph indicates the discriminatory value of SIRI for poor outcomes (grade A to C) at discharge in tSCI patients (Model 1). (B) The ROC of SIRI with adjustment for age and sex (Model 2). (C) The ROC of SIRI with adjustment for all confounding factor (Model 3). (ROC, receiver operating characteristic; TPR, true positive rate; FPR, false positive rate).
