¹Associations are shown for natural log-log models. Tobit regression was used to account for values below the limit of detection, indicated by number censored. Parameter estimates for beef intake reflect associations in women who reported beef consumption. Median servings (IQRs) of beef intake were 0.71 (1.68) for all subjects and 1.20 (1.75) for those who reported beef consumption. The median (IQR) serving of dairy was 2.05 (2.02). The sample includes all mothers who completed at least one 24-h recall. The β-coefficients represent the percentage increase in milk BCFAs (in mg/100 mL) for a 1% increase in dietary servings. One serving size is defined by the recommendations of the 2000 Dietary Guidelines for Americans (https://health.gov/dietaryguidelines/dga2000/document/frontcover.htm). BCFA, branched-chain fatty acid.
