The Association between Pregnancy and Risk for Alcohol Use Disorder – as assessed by an Odds Ratio (± 95% Confidence Intervals) – in the general population, cousins, siblings and monozygotic twins discordant for pregnancy, and within-individuals (comparing matched periods before and during pregnancy) for a first and second pregnancy. The odds ratios are all from the predicted model and are estimated from models without covariates. Sample sizes are based on individuals with alcohol use disorder registrations within each group (see Table 1); for cousins and siblings, these are from discordant pairs.
