Variability in Test Interval Is Linked to Glycated Haemoglobin (HbA1c) Trajectory over Time

Figure 1

Association between availability in testing interval (expressed as decile of the test interval standard deviation) and change in HbA1c concentration between and , stratified by baseline HbA1c: (a) 5.0–5.9% (30–41 mmol/mol), (b) 6.0–6.5% (42–47 mmol/mol), (c) 6.5–7.0% (48–53 mmol/mol), (d) 7.0–7.5% (54–58 mmol/mol), (e) 7.5–9.0% (59–75 mmol/mol), (f) 9.1–10.0% (76–86 mmol/mol), and (g) >10.0% (>86 mmol/mol).
