  1. Note: Factors simultaneously adjusted to calculate the odds ratios included gender, age classes, smoking history, hypertension, blood glucose classes, BMI classes, hypercholesterolemia and rural/urban areas. The upper limit and the lower limit of the 95% confidence intervals (CIs) were written in the brackets. Normal ECG was used as the reference. The middle age (45–59 years old) group and the older age (≥60 years old) group were compared with the young group (20–44 years old). The underlined odds ratios indicated the significant associations between the factors and the ECG findings
