Sources of data
This PASS is a population-based cohort study based on routinely collected data from administrative and medical registers in four Nordic countries: Denmark, Finland, Norway, and Sweden and will include all identifiable pregnancies between 2005 and up to 2015, followed up to 2016 (with actual period varying slightly by country)
11. Scope of the study

Primary scope : Disease epidemiology
12. Main objective(s)
What is the main objective of the study?
The study objectives are to describe the use of pregabalin exposure in pregnancy and to estimate the risk of major congenital malformations, birth outcomes other than congenital malformations and neurodevelopmental outcomes with the use of pregabalin.
Are there primary outcomes?Yes
major congenital abnormalities
Are there secondary outcomes?Yes
Neurodevelopmental outcomes
13. Study design
What is the design of the study?
Cohort study
14. Follow-up of patients
Will patients be followed up?Yes
Please describe duration of follow up
Prevalence at birth with outcomes identified at birth, and until the first birthday (inclusive)
through 2016 in Denmark, Finland and Norway and through 2014 in Sweden
15. Data analysis plan
Please provide a brief summary of the analysis method
Prevalence of each birth outcome will be computed as number of newborns with a given outcome divided by the total number of newborns at risk. For the outcomes of congenital malformations and stillbirth in the analysis not including pregnancies ending in 2nd trimester abortion the number of newborns at risk will be the total number of live or stillborn children.
Incidence rate of each postnatal outcome will be computed as the number of first-recorded events during the follow-up divided by the total person-time at risk contributed by each liveborn infant. The follow-up for each newborn will begin on the date of birth and will end on the date of a given postnatal outcome, emigration, death, or the end of the observation period.
Crude and adjusted prevalence ratios and 95% Wald confidence intervals (CIs) for each birth outcome and a given population/contrast will be estimated using log-binomial regression.
Crude and adjusted incidence rate ratios and 95% Wald CIs will be estimated
