(A) Receiver operating characteristic (ROC) curves of single laboratory indicators for the diagnosis of acute HCA. Monocyte-lymphocyte ratio (MLR) has a higher predictive value for HCA than C-reactive protein (CRP), neutrophil to lymphocyte ratio (NLR) and monocyte-leukocyte ratio (M%). (B) ROC curves of combined multiple laboratory indicators for the diagnosis of acute HCA. The area under the curve (AUC) of the best logistic regression model climbed to 0.706 (CRP + MLR, 95% confidence interval, 0.671–0.742)
