Study design details

• Main study objective:
  The aim of the study was to describe pregnancy outcomes in women exposed to prescription of dopamine agonists in EFEMERIS, and to compare with unexposed women.
• Outcomes:
  Pregnancy losses, birth defects, preterm births, low birth weight, psychomotor development.
• Data analysis plan:
  Maternal characteristics and adverse fetal outcomes in the two groups (“exposed” and “unexposed”) were described and compared by simple conditional logistic regression. Then, we used conditional logistic regression to analyze risks for each outcome associated with dispensation of dopamine agonists. To identify confounders, we used simple conditional logistic regression to evaluate the association between each potential confounder (dispensation of folic acid and progesterone during organogenesis, multiple births, preterm birth, gender, mother’s occupation, number of ultrasound scans during pregnancy, pathologies during pregnancy) and each outcome. For psychomotor development, the small sample sizes led us to use exact conditional logistic regression. For analysis of the risk of pregnancy loss, survival analysis was also used, as a sensitivity analysis, to take the time–dependant characteristics of exposure into account. Cox proportional hazard regression was applied.
