CI, confidence interval; CKMI, cardiovascular-kidney-metabolic index; ICU, intensive care unit; BMI, body mass index; CHD, coronary heart disease; CHF, congestive heart failure; WBC, white blood cell; RBC, red blood cell; HbA1c, hemoglobin A1c; ALT, alanine aminotransferase. Model A: unadjusted covariates. Model B: adjusted by age and BMI. Model C: adjusted by age, BMI, CHD, CHF, hypertension, diabetes, stroke, sepsis, WBC, RBC, hemoglobin, albumin, HbA1c, and ALT.
