From: Risk-adjustment of diabetes health outcomes improves the accuracy of performance benchmarking
Unadjusted and risk-adjusted funnel plots of mean LDL-Ch (mmol/L) levels. These funnel plots compare unadjusted and risk-adjusted clinical performance with regards to mean LDL-Ch (mmol/L) levels. 99.8% (outer limits) and 95% (inner limits) control limits are shown. (A) Mean unadjusted LDL-Ch (mmol/L) in patients with T2DM and (B) Mean risk-adjusted LDL-Ch (mmol/L) in patients with T2DM (adjusted for age, disease duration, disease severity, and fasting status); (C) Mean unadjusted LDL-Ch (mmol/L) in patients with T1DM and (D) Mean risk-adjusted LDL-Ch (mmol/L) in patients with T1DM (adjusted for disease duration and fasting status).
