Diagnosis Prevalence List
These numbers should reasonably reflect the relative prevalences of diagnoses among children in primary care practices, though they are based on studies that vary in design and populations and may involve assumptions about patient age distributions [Bocian: 1999]. Some listed conditions may not be considered medical diagnoses. Click Feedback for questions or to suggest better prevalence studies.
