Showing the number of congenital anomaly (CA) ( A) and congenital heart disease (CHD) ( B) cases at different ages using linked primary care data in ALSPAC. Age cut-offs are diagnoses in first year of life and then up until age 5, 15, 20 and 25. The age-25 column includes all diagnoses from the 2016 primary care extraction; therefore, some participants may be slightly older than 25, but younger than 26. Numbers are presented at the child level, so if a child had multiple anomaly diagnoses, they would only be counted once (at the time of their first diagnosis). For comparison, ( C) and ( D) show corresponding estimates for any CA and any CHD respectively from the Born in Bradford cohort primary care extraction up until age 5 (Adapted with permission from Bishop et al. (2014) ⁵. Bars show the number of cases in each age category and points show the cumulative number of cases. *Cell values <5 are suppressed for disclosure control purposes (may include 0).
