Univariate relationship between patient groups 2 and 1 (but considering only the data of the first 48 h in the latter)

Univariate relationship (expressed in box plots) between average BG sampling frequency () and GPI (top panel), APACHE II score () and glycemic penalty index (GPI) (middle panel), and type of illness and GPI (bottom panel) for patient group 2 and 1 (but considering only the data of the first 48 h in the latter). The p values of the null hypothesis that the GPI medians per group are equal are mentioned in each panel. A significant difference was found for the average blood glucose (BG) sampling frequency: the BG profiles with ≥ 0.5 h(i.e., time intervals less than 2 h) are related to stricter glycemic control (lower GPI).Copyright information:Taken from "Glycemic penalty index for adequately assessing and comparing different blood glucose control algorithms"http://ccforum.com/content/12/1/R24Critical Care 2008;12(1):R24-R24.Published online 26 Feb 2008PMCID:PMC2374580.
