Model 1: included 248 cycles in 142 female partners of men studied, adjusted for total energy intake, age, BMI, alcohol, caffeine, smoking status, total exercise time, Prudent dietary pattern, Western dietary pattern and female age; Model 2: included 219 cycles in 130 female partners of men studied, adjusted for total energy intake, age, BMI, alcohol, caffeine, smoking status, total exercise time, Prudent dietary pattern, Western dietary pattern and female dairy intake.
Tests for trend were performed using the median level of dairy in each quartile as a continuous variable in the model.
