Crude model: without adjustment.
Model 1: adjusted for age (categorial) and sex.
Model 2: adjusted for model 1 plus race, education, marital status, smoking history, drinking history, dietary intakes during the past 24 h (continuous), body mass index (categorial), hypertension, diabetes, albumin (categorial), albumin/globulin ratio (categorial), urinary albumin level (continuous), chronic kidney disease stages (categorial) as well as National Health and Nutrition Examination Survey cycle.
