Comparison of receiver operator characteristic (ROC) curves for predicting DCI using logistic regression model. Both unadjusted and adjusted for covariates. The larger area under the ROC curve indicates superiority of %ΔCPPopt < − 10 mmHg over %dHP; also, inclusion of covariates improves the discriminative ability of the markers. Adjusted variables including ICP, Hunt-Hess Score, and mFisher Score
