Fish and red meat intake 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). 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. *P < 0.05 when compared with the lowest category of intake.
