Table 3 Optimal sphericity cutoff values for each of the receiver operating characteristic (ROC) curves for lymph nodes with a short-axis diameter ≥ 4 mm, 5 mm, or 6 mm, as well as the sensitivities and specificities of those values
From: Sphericity of lymph nodes using 3D-CT predicts metastasis in lung cancer patients
Short-axis diameter | Sphericity cut-off value | Sensitivity | Specificity |
|---|---|---|---|
4 mm | 0.63 | 76.1% | 77.3% |
5 mm | 0.63 | 84.1% | 89.3% |
6 mm | 0.67 | 53.9% | 97.8% |
