Scatterplot of the various insulin-related measures in serum in the two study groups. a S-insulin. b S-insulin c-peptide. c S-IGF. d S-IGFBP3. e S-glucose. The center of the centroid reference lines represents the mean value in each group (dotted lines). P-values were determined using t-tests. Units are given by the x-axis and y-axis. All values on the x-axis are at admission, and the y-axis values represent pre-operative measurements. Red, carbohydrate group; blue, fasting group; S, serum; Preop., pre-operatively; IGF, insulin-like growth factor; IGFBP3, IGF-binding protein 3
