Abbreviations: CCHD = critical congenital heart defect; CI = confidence interval; NBDPN = National Birth Defects Prevention Network.

Note: Programs with active case-finding methodology that ascertained more than live births: Arizona, California, Delaware, Georgia (Metropolitan Atlanta), North Carolina, Puerto Rico, South Carolina, Texas, and Utah (total live births = 3,817,972). Programs provided the code ranges used to define each birth defect where they differed from those requested by the NBDPN (appendix 3.1). If a program defined a birth defect using a different code range then the created estimates use the program-specific code range, when no alternate code range was specified the NBDPN code range was used. Cases were included when gestational age was greater than or equal to 20 completed weeks gestation. If gestational age was missing birth weight was used as a proxy.

^aThe CCHDs column displays a count, prevalence, and CI for of cases with any of the individual CCHDs presented in the article. Cases with more than one CCHD code were counted only once in this summarized category.

^bCI calculated using exact Poisson methodology.

^cCounts across subgroups may not add to the total due to other/unknown categories (not shown).
