  • Numbers show lung function parameter relative to value at the median AChE/Hb in the analysis, with 95% CI.

  • Absolute lung function measures: All analyses (including unadjusted) include sex, age and height as covariates. Basic covariate set=age, sex, height, pack-years of smoking, cumulated lifetime hours of cooking. Extended covariate set=basic set+BMI, years of full-time education.

  • Z-scores: Basic covariate set = age, sex, pack-years of smoking, cumulated lifetime hours of cooking. Extended covariate set=basic set+BMI, years of full-time education.

  • AChE/Hb, erythrocyte acetylcholinesterase normalised by haemoglobin concentration; BMI, body mass index.
