Threshold | Sensitivity | Specificity | PPV | NPV | # of Controls | # of Cases |
---|---|---|---|---|---|---|
PFV ≥100 cm3 | 37.0* | 78.88 | 46.6 | 71.4 | 31 | 27 |
PFV ≥125 cm3 | 21.9* | 91.88 | 57.1 | 70.2 | 12 | 16 |
PFV ≥150 cm3 | 12.3* | 97.38 | 69.2 | 68.9 | 4 | 9 |
TFV ≥175 cm3 | 47.9 | 68.58 | 43.2 | 72.5 | 46 | 35 |
TFV ≥200 cm3 | 41.1 | 80.88 | 51.7 | 73.3 | 28 | 30 |
TFV ≥225 cm3 | 30.1 | 87.08 | 53.7 | 71.3 | 19 | 22 |
Significantly different (p < 0.05) across 3 cut points.
NPV = negative predictive value; PFV = pericardial fat volume; PPV = positive predictive value; TFV = thoracic fat volume.
