Table 6 ROC analysis for clinical and echocardiographic predictors of coronary tortuosity

From: Coronary tortuosity relation with carotid intima-media thickness, coronary artery disease risk factors, and diastolic dysfunction: is it a marker of early atherosclerosis?

Variable AUC (95% CI) P value Sensitivity (95% CI) Specificity (95% CI)
Clinical
 Total Cholesterol (> 168 mg/dL) 0.72 (0.59–0.83) < 0.001 73.3% (54.1–87.7) 63.3% (43.9–80.0)
Echocardiographic
 A velocity (> 72.8 cm/s) 0.88 (0.77–0.95) < 0.001 73.3% (54.1–87.7) 96.7% (82.7–99.4)
 DT (≤ 155 ms) 0.86 (0.74–0.93) < 0.001 66.67% (47.2–82.7) 96.6% (8.7–99.4)
