Total meat, eggs, and vegetable sources of protein-rich foods (beans, nuts, and soy) and clinical outcomes analysis in the EARTH Study (n = 351 women; 598 cycles). Data are presented as predicted marginal means with 95% CIs adjusted for total daily calories, age, BMI, race, smoking status, daily supplemental dietary folate, supplemental vitamin B-12, supplemental iron intake, supplemental ω-3 (binary, yes/no), and prudent and Western dietary patterns (excluding meats), with all continuous variables at their mean level and all categorical variables at their weighted average level. All analyses were adjusted for all the other protein-rich foods. All outcomes were analyzed using generalized linear mixed models with random intercepts, binary distribution, and logit link function. Test for trend was performed using a continuous variable for the median number of servings per day for each quartile of the corresponding meat intake in the regression models.
