• Design, comparison groups
• Selection bias
• Implementation

Analysis
• Multilevel regression models used to estimate the association between presence of school garden and student nutrition indicators
• Analyses control for student characteristics (sex, age, ethnicity, socioeconomics) and school characteristics (size, funding, decile)
