Education (No qualifications vs at least O-level^‡)	−0.017 (−0.06- 0.03)	0.5	−0.02 (−0.063- 0.02)	0.4	−0.016 (−0.06- 0.03)	0.5
Deprivation level (Highly deprived vs less deprived^‡)	0.025 (−0.027- 0.08)	0.4	0.026 (−0.026- 0.08)	0.3	0.024 (−0.029- 0.08)	0.4

Social class (Manual vs non-manual^‡)	0.025 (−0.014- 0.06)	0.2	0.002 (−0.037- 0.04)	0.9	−0.014 (−0.053- 0.03)	0.5

Deprivation level (Highly deprived vs less deprived^‡)	−0.005 (−0.055- 0.04)	0.8	−0.007 (−0.057- 0.04)	0.8	−0.006 (−0.056- 0.04)	0.8

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.
