tblNEWBORN_ABNORM - Abnormalities

holds information related to abnormalities of newborns

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.

Please also read the notes on pregnancy tables.
