Cut-off value of left atrial volume index in predicting pulmonary hypertension
| Cut off of LAV index | Sensitivity (%) | Specificity (%) | LR + | LR - | PPV (%) | NPV(%) |
|---|---|---|---|---|---|---|
| ≥60 ml/m2 | 92.7 (80.1–98.5) | 50.4 (40.9–60.0) | 1.9 (1.5–2.3) | 0.2 (0.1–0.4) | 40.4 (30.4–51.0) | 95.0 (86.1–99.0) |
| ≥65 ml/m2 | 85.4 (70.8–94.4) | 57.5 (47.9–66.8) | 2.0 (1.6–2.6) | 0.3 (0.1–0.5) | 42.2 (31.4–53.5) | 91.5 (82.5–96.8) |
| ≥70 ml/m2 | 70.7 (54.5–83.9) | 63.7 (54.1–72.6) | 2.0 (1.4–2.7) | 0.5 (0.3–0.8) | 41.4 (29.8–53.8) | 85.7 (76.4–92.4) |
