Logistic Regression: Probability of Developing Moderate to Severe MR in This Patient Sample
| Univariate Logistic Regression | Multiple Variable Logistic Regression* | |||
|---|---|---|---|---|
| Variable | OR (95% CI) | P | OR (95% CI) | P |
| Patient group DCM vs IWMA | 3.95 (1.8–9.7) | 0.003 | 1.7 (0.5–6.5) | 0.4108 |
| EF <35% | 10.8 (2.58–43.5) | 0.0011 | 4.9 (0.3–18.0) | 0.7303 |
| Annular dilation (>9 cm2) | 12.2 (2.86–52.0) | 0.0007 | 2.0 (0.2–18.1) | 0.1 |
| ESV >80 mL | 18.5 (4.3–83.3) | 0.0001 | 3.7 (0.3–47.0) | 0.3098 |
| Leaflet area-to–closure area ratio <1.7 | 35.7 (4.27–333.3) | 0.001 | 23.2 (2.0–49.1) | 0.02 |
| Tethering length >3.9 cm | 6.5 (1.72–25.0) | 0.006 | 2.2 (0.2–23.0) | 0.5225 |
OR indicates odds ratio; CI, confidence interval; EF, ejection fraction; and ESV, end-systolic volume.
