by congenital condition
What you will find here
In these views, congenital conditions are presented one at the time, with data from all programs.
The structure is simple:
- programs are grouped by geography, which usually correlates with country income level
- within each geography, programs are listed by decreasing prevalence of the condition
Comparisons among are tricky, however, and must be interpreted with great care and background knowledge.
- More often than not, variations in rates derive from differences in methodology rather than in true occurrence (birth prevalence). Examples of such differences include the inclusion or not of terminations of pregnancy or stillbirths, the number and types of data sources, and approach to population coverage (e.g., population vs. hospital based).
- The charts provide two methodologic indicators for each program (whether population- or hospital-based, and whether they include terminations of pregnancy), but be sure to review the methods of each program and the comments of program staff to avoid over- or misinterpreting these charts.
