HRs for all-cause and cause-specific mortality by glycated haemoglobin and self-reported diabetes category.

1 Normoglycaemic/no diabetes: those who neither indicated diabetes nor had a raised HbA1C measurement (<39mmol/mol (<5.7%))
2 Pre-diabetes: those without diabetes but an HbA1C measurement within the pre-diabetic range (39-<48mmol/mol (5.7-<6.5%)).
3 Undiagnosed diabetes: those with raised HbA1C (≥48mmol/mol (≥6.5%)) without diagnosed diabetes
4 Controlled diabetes: those with diabetes and an HbA1C <39mmol/mol (5.7%).
5 Diabetes and moderately raised HbA1C: those with diagnosed diabetes and an HbA1C 39-<48mmol/mol (5.7–6.49%).
6 Uncontrolled diabetes: those with diagnosed diabetes and raised (≥48mmol/mol (≥6.5%)) HbA1C.
