Multivariate logistic regression analysis to detect LVH

BMI, body mass index; BUN, blood urea nitrogen; CI, confidence interval; CTR, cardiothoracic ratio; HDL, high-density lipoprotein; LDL, low-density lipoprotein; LVH, left ventricular hypertrophy; N/A, not applicable; OR, odds ratio; SBP, systolic blood pressure; SLVA, Sokolow-Lyon voltage amplitude.

^∗To build an easy-to-use screening rule to detect LVH, the score was rendered by multiplying the OR by an arbitrary number of 0.39 and rounding it up.
