*Each hazard ratio was computed using a restricted cubic spline model with the median R-wave Onset to R-peak (A) value of 24 ms as the reference, and for R-peak to R-wave End (B), a median value of 18 ms was used as the reference. Models included the following; age, sex, race, heart rate, smoking, systolic blood pressure, diabetes, body mass index, low-density lipoprotein cholesterol, antihypertensive medication use, and left ventricular hypertrophy. Dotted-lines represent the 95% confidence interval.
