BMI = body mass index; CI = confidence interval; aFOR = adjusted fecundability odds ratio.

aEach partner is modeled alone (eg, sex stratified).

bAdjusted for race/ethnicity, education, income, age, alcohol use, caffeine use, BMI in each partner.

cAdjusted for race/ethnicity, education, income, age, alcohol use, caffeine use, BMI, blood cadmium in each partner.

dBoth partners are modeled together (eg, accounting for the other partner’s tobacco use and sociodemographic characteristics).

eAdjusted for both partners’ race/ethnicity, education, income, alcohol use, caffeine use, BMI, couple’s mean age, difference in partners’ ages.

fAdjusted for both partners’ race/ethnicity, education, income, alcohol, caffeine, BMI, blood cadmium, couple’s mean age, difference in partners’ ages.
