Table 2 Multinomial logistic regression models of dietary Fiber intake and AAC groups

From: Dietary fiber and prevalence of abdominal aortic calcification in the United States (from the national health and nutrition examination survey data [2013–2014])

  1. Crude adjusted for no variable. Model 1 adjusted for age, sex and ethnicity (non-Hispanic White, non-Hispanic black, Mexican American/Hispanic, and other races). Model 2 further adjusted for body mass index (continuous), education (less than high school and higher than high school), diabetes mellitus (yes and no), hypertension (yes and no), smoking (yes and no), total cholesterol /high density lipoprotein cholesterol (continuous), serum albumin (continuous), serum creatinine (continuous), serum total calcium (continuous), serum phosphorus (continuous), white blood cells (continuous), total 25-hydroxyvitamin D (continuous), and Caloric intake (continuous). * P < 0.05; ** P < 0.01; *** P < 0.001
