ROC curve of total XRS to predict intensive care necessity. The cut-off value of XRS in distinguishing patients who needed intensive care in the follow-up period was 6 (AUC = 0.933, 95% CI = 0.886 - 0.979). This cut-off value had 100% sensitivity, 81% specificity. AUC, Area under curve; CI, Confidence interval; ROC, Receiver operator characteristics
