Bonnot, 2003	case control	The medical records are checked to obtain data on treatment intake and other exposures or risks.	After having defined a population, often on geographical criteria, these networks set up birth observatories in order to exhaustively identify neonatal malformations in their reference population.	Adjusted for age and parity.
Calderon-Margalit, 2009	prospective cohort	Participants were interviewed during a prenatal visit prior to 20 weeks of gestation by trained research personnel using a structured questionnaire. Data on medications used during pregnancy were retrieved from both questionnaires and medical records.	Information on pregnancy outcome was ascertained by reviewing hospital labor and delivery medical records and clinic records after delivery.	Adjustments for maternal age, race, years of education, marital status, smoking during pregnancy, preeclampsia, parity, and singleton/multiple pregnancy.
Laspro, 2024	nested case control	Gestational medication use was identified by medications, prescribed, provider-administered, or reported use by mothers at any point during pregnancy.	Oral cleft cohorts were isolated using a combination of ICD codes, from the EPIC medical records.	None.

The National Birth Certificate Application (BCA) database that includes notably gestational age at birth, birth date of newborns, singleton or multiple pregnancy, birthweight, and birth outcomes.	Siblings. Singletons only. Adjusted for maternal age, sex of the infant, birth year, psychiatric medical conditions, tobacco use, alcohol use, drug abuse, and obstetric comorbidity index scores.

The National Birth Certificate Application (BCA) database that includes notably gestational age at birth, birth date of newborns, singleton or multiple pregnancy, birthweight, and birth outcomes.	Singletons only. Propensity score (PS-FSW) to control for maternal age and nationality, sex of the infant and year of birth, indications for use (eg, anxiety, insomnia, depression, schizophrenia, epilepsy, and bipolar disorder), lifestyle factors (obesity, tobacco, alcohol, ...), chronic maternal comorbidities (hypertension, diabetes, ...), medication use, obstetric comorbidity, health-care use.
Meng b, 2023	other	The National Health Insurance (NHI) database that comprises anonymized prescriptions for more than 99% of the population in Taiwan.	The National Health Insurance (NHI) database that comprises anonymized health insurance claims for visits and procedures for more than 99% of the population and the Birth Certificate Application (BCA) database (all live births and stillbirths > 20 gestational weeks or birth weight > 500g).	Controls matched for the birth year and a disease risk score (based on age, psychiatric medical conditions, lifestyle factors (obesity, tobacco, alcohol, drug misuse), chronic comorbidities (diabetes, hypertension, hyperlipidemia, …), medication use, and health care use). Adjusted for the comedication use (antidepressants, opioid analgesics, anticonvulsant, Z-hypnotics, and other anxiolytics).
Noh, 2022	population based cohort retrospective	The Health Insurance Review and Assessment Service (HIRA) database that comprises notably healthcare utilization (e.g., drug prescription and medical procedure).	Major congenital malformations were identified by diagnostic records, according to the ICD-10 codes defined by the European Surveillance of Congenital Anomalies classification.	Exclusion of exposures to known teratogens during 1st trimester. Adjusted for maternal age, type of insurance, maternal psychiatric conditions (e.g., bipolar disorder, depression/mood disorder, anxiety, and sleep disorder), maternal conditions (e.g., epilepsy, headache, diabetes, hypertension), parity, plurality, concomitant medications (e.g., antidepressants, ...), and healthcare utilization.
Sheehy, 2019	nested case control	The Quebec Public Prescription Drug Insurance Plan database (drug name, start date, dose, and duration).	The data sources included the medical service database the Régie de l’assurance maladie du Québec (diagnoses, medical procedures, ...) and the MedEcho database (in-hospital diagnoses and procedures, including gestational age for planned abortions, spontaneous abortions, and deliveries).	Adjusted for (1) maternal sociodemographic variables (2) maternal chronic conditions (hypertension, diabetes, depression/anxiety, alcohol ...), (3) health care resources utilization, (4) pregnancy-associated variables, (5) concomitant exposure to antidepressants and/or antipsychotics. Matched by gestational age and calendar year. Exclusion of women with epilepsy and exposed to known teratogens.
Tinker, 2019	case control	Detailed information notably about medication use during pregnancy (including over-the-counter (OTC) and prescription medication) was collected from the mothers via computer-assisted telephone interviews conducted between 6 weeks and 24 months after the estimated date of delivery (EDD).	Cases were identified in the The National Birth Defects Prevention Study. The NBDPS clinical data for birth defect cases were abstracted from medical records and classified by clinical experts. Controls were selected from birth certificates or hospital records in the same area.	For associations with at least 5 exposed cases: adjusted for maternal age, race/ethnicity, maternal education, any maternal cigarette smoking or antidepressant medication use in the first trimester (no adjustment if < 5 cases). Exclusion of mothers who reported use of an antiepileptic other than a benzodiazepine in the first trimester.
