Cox Multivariate predictors of sudden death at five years
| Variable | Mean (SEM) parameter estimates | χ2 | Cox multivariate analysis hazard ratio (95% CI) | p Value |
|---|---|---|---|---|
| P values are based on Cox proportional hazards model. | ||||
| NSVT, non-sustained ventricular tachycardia; QTc, QT interval corrected for rate. | ||||
| Cardiothoracic ratio (10% increase) | 3.75 (0.96) | 15.3 | 1.43 (1.20 to 1.71) | 0.001 |
| NSVT (present) | 0.71 (0.24) | 8.7 | 2.03 (1.27 to 3.25) | 0.003 |
| QRS dispersion (10% increase) | 1.10 (0.36) | 9.2 | 1.11 (1.04 to 1.19) | 0.002 |
| QTc dispersion V1–V6 (10% increase) | 0.36 (0.17) | 4.4 | 1.03 (1.00 to 1.07) | 0.035 |
