Multivariate-adjusted hazard ratiosa comparing subjects with J-point elevation in any lead to subjects without J-point elevation, stratified by race and sex simultaneously
| White males HR (95% CI) (n = 5180) | White females HR (95% CI) (n = 5888) | Black males HR (95% CI) (n = 1527) | Black females HR (95% CI) (n = 2546) | |
|---|---|---|---|---|
| Sudden cardiac death | 1.51 (0.91–2.52) | 8.77 (3.19–24.13) | 0.82 (0.47–1.47) | 1.33 (0.59–3.01) |
| Fatal/non-fatal CHD | 1.11 (0.90–1.37) | 1.32 (0.77–2.25) | 0.80 (0.62–1.04) | 1.47 (1.03–2.09) |
| All-cause mortality | 1.14 (0.97–1.35) | 0.93 (0.61–1.39) | 0.94 (0.79–1.12) | 0.96 (0.74–1.25) |
aBased on Model 3: Cox's proportional hazards model, adjusted for age, sex, race, heart rate, systolic blood pressure, BMI, serum low-density lipoprotein, diabetes, presence of major ECG abnormality, Cornell's voltage for LVH, previous CHD, history of angina or stroke, smoking status, physical activity, serum potassium, an interaction term between J-point elevation status and race, and an interaction term between J-point elevation status and sex.
