Unadjusted, Age‐ and Sex‐Adjusted, and Multivariable HRs for SCD of STERP

	Group A	Group B	Group C
Person‐years	4816.8	8951.1	117210.7
Number at risk	228	615	6243
Number with SCD	7 (3.1%)	11 (1.8%)	39 (0.1%)
Age‐ and sex‐adjusted HR (95% CI)	4.1 (1.8–9.6)	2.4 (1.1–5.1)	1
Multivariable HR (95% CI)	3.9 (1.7–9.0)	2.5 (1.2–5.3)	1

HRs are for group A (J point amplitude >0.2 mV) and group B (J point amplitude >0.1 to <0.2 mV) versus group C (J point amplitude <0.1 mV). The multivariable HR is adjusted for age, sex, systolic blood pressure, antihypertensive medication use, smoking status, and diabetes mellitus. HR indicates hazard ratio; SCD, sudden cardiac death; STERP, atypical ST‐segment elevation in the right precordial leads.
