Unadjusted and risk-adjusted rates of severe hypoglycaemia (%). These funnel plots compare unadjusted and risk-adjusted clinical performance with regards to rates of severe hypoglycaemia (proportion of patients who experienced one or more episodes of severe hypoglycaemia within the previous 12 months). 99.8% (outer limits) and 95% (inner limits) control limits are shown. (A) Unadjusted rates (%) in patients with T2DM and (B) Risk-adjusted rates (%) in patients with T2DM (adjusted for disease duration); (C) Unadjusted rates (%) in patients with T1DM and (D) Risk-adjusted rates (%) in patients with T1DM (adjusted for disease duration, BMI and smoking history).
