Association of each potential predictor with stroke occurrence in the overall study population (n=698)
| Potential predictor | Stroke present (n=219) | Stroke absent (n=479) | Odds ratio (95% CI) |
|---|---|---|---|
| The odds ratios are adjusted for age (except the odds ratio for age). | |||
| MI, myocardial infarction; ECG, electrocardiogram; LVH, left ventricular hypertrophy. | |||
