Model based on equation shown in online supplementary file and includes random intercept for LSOA, and fixed effects for percent of population aged 50+ years, percent female, percent unemployed and two spline terms for time (full model results are given in online supplementary file).
Model based on 98 Knowsley and 490 control LSOAs, and 6468 observations.
CVD, cardiovascular disease; DiD, difference-in-differences; LSOA, lower-layer super output area.
