Opportunities for Examining Child Health Impacts of Early-Life Nutrition in the ECHO Program: Maternal and Child Dietary Intake Data from Pregnancy to Adolescence

“Select deidentified data from the ECHO Program are available through NICHD's Data and Specimen Hub (DASH) ( https://dash.nichd.nih.gov ). Information on study data not available on DASH, such as some Indigenous datasets, can be found on the ECHO study DASH webpage ( https://dash.nichd.nih.gov/study/417122 ).”

The data-availability statement points to a repository record (DASH) with a link, which is Colavizza category 3. [majority verdict 'yes' (4/5 passes agreed)]
