Beta coefficients for mean percentages of active patients with T2D in their general practice record from September 2020 to June 2022. Data are beta coefficient (95% CI) for mean percentage of patients with an HbA1c test result in the past 15 months (see table 3) after correction for any linear changes over time.

*Corrected for time trend.

BMI, body mass index; T2D, type 2 diabetes.
