Journal Article
Quinn, L., Yu, D., Lynch, M., P Jordan, K., Wilkie, R., & Peat, G. (2025). An application of matching algorithms to generalize small-area estimates of chronic pain prevalence to neighbourhoods across England. Journal of Public Health, 1-9. https://doi.org/10.1093/pubmed/fdaf002

Background
Local decision-makers lack granular data on the prevalence of chronic pain in their populations. We applied matching methods to generalize estimates from one local survey in England to other neighborhoods across the country with a similar...
