NOTE: In utero exposures were simultaneously included in model.
Model adjusted for clinical site (California/Utah), currently smoking (yes/no), age at menarche (years) and BMI (weight in kg/height in m2).
As lower birth is associated with increased risk of endometriosis in previous studies, birth weight entered the model so that the estimated OR/AOR confers the effect of every pound less in weight.
