Hazard ratios for lower limb amputation according to combinations of HbA1c and age. The hazard ratio (HR) for those aged ≥60 years with HbA1c < 8.0% was 3.77 (95% confidence interval (CI) 1.09–13.04) and the HR for those aged < 60 years with HbA1c ≥8.0% was 3.96 (95% CI 0.93–16.78). The HR for those aged ≥60 years with HbA1c ≥8.0% was 27.81 (95% CI 6.54–118.23) compared with those aged < 60 years with HbA1c < 8.0% (reference group). Adjusted for diastolic blood pressure
