Unadjusted and risk-adjusted funnel plots of mean systolic blood pressure (mmHg) measurements. These funnel plots compare unadjusted and risk-adjusted clinical performance with regards to mean systolic blood pressure (SBP) measurements (mmHg). 99.8% (outer limits) and 95% (inner limits) control limits are shown. (A) Mean unadjusted SBP (mmHg) in patients with T2DM and (B) Mean risk-adjusted SBP (mmHg) in patients with T2DM (adjusted for age, BMI and disease severity); (C) Mean unadjusted SBP (mmHg) in patients with T1DM and (D) Mean risk-adjusted SBP (mmHg) in patients with T1DM (adjusted for sex, age, BMI and disease duration).
