  1. aResults from regression models, adjusted by age, years working, and BMIbEstimates are expressed as Cumulative Odds Ratios for “lower workload capacity “and “lower financial wellbeing status “, and as Odds Ratios for “reliance on others”
  2. cEstimates show multiplicative change in odds per 10-unit increase in WOMAC score
  3. dBecause of the low number of respondents producing these commodities, stratified analyses are limited in power and data for these commodities should be considered dubious
