Abnormalities in newborns are recorded here, one abnormality per row. The absence of a record is to be interpreted as "unknown whether the abnormality existed" since most cohorts only record positive events.
Note: Fields marked bold form the unique identifier for a record of the table. For multiple abnormalities, please specify one record per abnormality.
