  • *Statistical significance: printed in bold if p≤0.05.

  • †Multilevel linear regression models controlled for neighbourhood demographic composition; constant: men, age group 0–4 years, year 2013, rural area, very high status neighbourhood.

  • ICC, intraclass correlation between PCS catchment areas: the relative contribution of PCS catchment area to the residual variance; PCS, primary care service; SES, socioeconomic status.
