Fig. 2From: The relationship between longer leukocyte telomeres and dNCR in non-cardiac surgery patients: a retrospective analysisROC curve for incidence prediction of dNCR in elderly patients following non-cardiac surgery. ROC curve analysis was performed for the LTL with dNCR. The area under the ROC curve of the duration of the LTL in the dNCR group was 0.791 (95% CI, 0.722–0.859). The optimal cut-off value was 0.959, with a sensitivity of 87.5% and a specificity of 64.7%Back to article page
