Regression coefficients are shown as the difference in mmol/L from the reference category, adjusted for the other factors in the model. ^‡Reference category. Predictor variables: Social class- non-manual = social classes I, II and III non-manual, manual = social classes III manual, IV and V. Education- at least O level, no qualifications. Deprivation level- based on Townsend deprivation scores: < 0 = less deprived, > 0 = highly deprived.
