*Estimate obtained from model adjusting for baseline total income only.
†Estimate obtained from model adjusting for baseline total income, age group, sex, ethnicity, chronic conditions, deprivation, region and industry.
‡A small constant was added to each participant’s work income so that the geometric mean could be calculated for participants with no work income.
