Fig. 3From: Liraglutide improves the beta-cell function without increasing insulin secretion during a mixed meal in patients, who exhibit well-controlled type 2 diabetes and coronary artery diseaseThe hyperbolic relationship between Btotal and ISIComposite—Open circles represents all pretreatment values, i.e. baseline values combined with values after wash-out before beginning of period 2. The hyperbolic function is evident for both groups and for all pretreatment values. Fitted (all); R2 = 0.81, fitted (baseline):R2 = 0.8, fitted (washout); R2 = 0.83. Treatment effect is indicated by square and triangle (liraglutide vs. placebo), beginning and end of treatment are depicted by arrowsBack to article page
