Table 3 Baseline CMAQ-urban and LHEM-adjusted CMAQ-urban pollutant concentrations (µg/m3) linked to ELSA respondents’ postcodes of residence, alongside overall IQRs per pollutant accounting for inter- and intra-respondent measurements and Spearman correlation coefficients between assigned residence-based CMAQ-urban concentrations and LHEM-adjusted estimates.
