The ROC curves of the TBM diagnostic model in the derivation (A) and validation (B) cohorts. The ROC curves show the specificity and sensitivity of predicting TBM in the derivation and validation cohorts based on the model output. These values indicate the good discrimination ability of the diagnostic model. AUC: area under the curve, CI: confidence interval, ROC: receiver operating characteristic, TBM: tuberculous meningitis
