a,bMeans on the same row with different superscript letters were significantly different (P < 0.05). SD = standard deviation. PA = physical activity. Educ = education level. Tertiles were based on cups of beans consumed per 1000 kcal. There were 82 subjects in each tertile. Means on the same row as the covariate(s) were adjusted for the covariate(s).
