^aAdjusted for retirement age, birth cohort, highest educational qualification, gender, practice effects, spouse employment status, employment grades, still working in the civil service, job demands, job decision latitude, smoking status, alcohol consumption, depressive symptoms, systolic blood pressure, diastolic blood pressure, body mass index, total blood cholesterol, coronary heart disease, stroke, malignant cancers, and diabetes/intermediate hyperglycaemia

^bCalculated as ‘slope after retirement’ minus ‘slope before retirement’

^cCalculated as ‘slope change’ divided by ‘slope before retirement’ and multiplied by 100%
