Models adjusted for maternal age, pre-pregnancy BMI, parity, marital status, education, cigarette and alcohol use, comedication use (NSAIDs, acetaminophen, opioids, antidepressants), depressive and anxiety symptoms.
Marginal structural models weighted with stabilized inverse probability of treatment weights, constructed at each time point using baseline confounders, time-invariant confounders, and medication history.
