 Response: The uniqueness of this study, is that we for the first time have day-to-day recordings of symptoms and use og local treatment during the first 3 years of life showing the disease peaks at 2 years of age and children start outgrowing thereafter.Previous studies including our own have analyzed eczema at a certain age.Since eczema is highly variable over time, our disease description is novel.This has allowed us a more reliable analyses of factors determining eczema in young children 

MedicalResearch.com: What should readers take away from your report?

Response: What we see it that eczema is determined by genetics and with no know external factors causing or deteriorating the severity.

 MedicalResearch.com: What recommendations do you have for future research as a result of this work?
