From: Diaphragm thickness and ICU admission risk in elderly COVID-19 patients: a CT-based analysis
Receiver operating characteristic (ROC) curve of right diaphragm thickness (DT) for predicting ICU admission rate. Receiver operating characteristic analysis to assess the predictive power of right DT revealed a cut-off value of 1.8 mm (AUC = 0.632, 95% CI [0.558–0.701] p = 0.009) for ICU admission rate. AUC: area under the curve, CI: confidence interval
