*Non-matched pregnancy outcome is defined as no pregnancy outcome reported in the pregnancy history survey within ±30 days of each outcome in the prospective data
~Multivariable logistic regression model with generalized estimating equations, to account for correlation associated with reporting of ≥1 singleton pregnancies for each woman, to estimate adjusted odds ratios and 95% confidence intervals of non-matched pregnancy outcomes by participant characteristics
