Results presented are median (25th, 75th percentiles) for continuous or percentage for categorical variables. Low Nt-proBNP defined as the lowest sex-specific quartile (≤ 7.3 pg/ml for men; ≤ 19.4 pg/ml for women). Total n for HOMA-IR = 2,710. Total n for LV mass index and LVEF = 2,549. Med = medication, BPM = beats per minute, BP = blood pressure, BMI = body mass index, HOMA-IR = homeostatic model assessment for insulin resistance, eGFR = estimated glomerular filtration rate, LV = left ventricular. P < 0.0001 for all between group comparisons, except female (P = 0.017).
