Receiver operating characteristic curve analysis of Thompson score as a predictor of short-term outcome. The area under the curve was 0.93 (95% confidence interval 0.86-0.99). The black circle and square indicate cutoff points of 4 and 5, respectively. When the cutoff value was 4, the sensitivity and specificity were 90.9% and 83.0%, respectively, and the positive and negative predictive values were 52.6% and 97.6%
