Unadjusted and adjusted (for QRISK3 risk factors) HRs of composite fatal/nonfatal CVD by deciles of baseline HbA1c in those without baseline diabetes (n = 355,260) and in participants with undiagnosed diabetes (n = 2,573) or diagnosed diabetes (n = 16,596). For simplicity, categories are depicted only as mmol/mol. The dashed line represents ≥48 mmol/mol (6.5%). Please note all results referent to decile 2 (30.4–32.0 mmol/mol).
