aData are presented as predictive marginal means adjusted for age, BMI, infertility diagnosis, race, smoking status, alcohol, caffeine, calories, folate and Vitamin B12 intake and dietary patterns, with continuous covariates at their mean level and categorical measures estimated at their reference level.
bTests for trend were performed using the median level of caffeine and alcohol intake in each group as a continuous variable in the model.
