Congenital diaphragmatic hernia in a middle-income country: persistent high lethality during a 12-year period.

Database used for analysis of the manuscript entitled: "Congenital diaphragmatic hernia in a middle-income country: persistent high lethality during a 12-year period". The aim of the study was to analyze, in São Paulo state of Brazil, the temporal trends of incidence, neonatal mortality and lethality of congenital diaphragmatic hernia (CDH) and its subgroups (isolated CDH, CDH associated to chromosomal anomaly and CDH associated to non-chromosomal anomalies) and identify the time to congenital diaphragmatic hernia-associated neonatal death.
