Mean park satisfaction measures among adult residents living near study parks before and after CPI park renovations. Means by intervention group (green square = intervention, grey circle = control) and 95% confidence intervals (vertical bars) were estimated using linear GEE models that included variables for time (pre-renovation vs. post-renovation), intervention group (renovated vs. control parks), and an interaction between time and intervention group (the DID estimator), and additionally adjusted for age group, BMI category, annual household income, public housing, marital status, and children in household. An asterisk denotes a significant (p < 0.05) DID estimator. BMI body mass index, CPI community parks initiative, DID difference-in-differences, GEE generalized estimating equations.
