Exclusion Criteria for Abstracts

• Addressed age groups beyond infancy
• Reflected funding of a symposium or an intramural project ($0 noted on abstract)
• Reflected a parent abstract whose subproject abstract also appeared in the search (we excluded the parent abstract and used only the subproject abstract to avoid duplication)
• Did not contain written description/specific aims of the proposed project or contained unclear aims, which precluded the ability to perform content analysis
