Mortality risk by HbA1c categories. Cox proportional hazards regression according to HbA1c categories, unadjusted (A) and adjusted for age and gender (B), plus cardiovascular disease (CVD) risk factors (C), plus complications/comorbidities (D). HRs (95% CI) for mortality are shown for each HbA1c category. HbA1c = haemoglobin A1c; HR = hazard ratio; CI = confidence interval; C1 = HbA1c <6.5%; C2 = HbA1c 6.5%–7.49%; C3 = HbA1c 7.5%–8.49%; C4 = HbA1c ≥8.5%; ref*, the asterisk indicates the reference category.
