Figure 4 Receiver operating characteristic (ROC) curve of diaphragm ultrasound parameter (DTF) for diagnosing frailtyThe ROC curve displays the diagnostic performance of diaphragm thickness fraction in distinguishing frail from non-frail elderly patients. The area under the curve (AUC) was 0.846 (95% CI: 0.7602–0.9311), with a sensitivity of 81.32% and specificity of 78.33%.
