- NPV: negative predictive value; PPV: positive predictive value
- we evaluated the predictive performance, including sensitivity, specificity, and positive and negative predicted values, utilizing the threshold criteria, which the HACOR score versus those for the ROX index as follows: > 5 versus < 2.85 at 2 h; > 5 versus < 3.47 at 6 h; and > 5 versus < 3.85 at 12 h, respectively. Because of limited evidence regarding the cutoff points at 24 and 48 h, we employed the threshold established at 12 h
