Results of the meta-analysis conducted on the time spent in CCU/ICU, for patients with and without tight glycaemic control, following cardiac surgery. This figure illustrates the forest plot created from the meta-analysis of total time spent in CCU or ICU following cardiac surgery, for those patients with and without tight glycaemic control. Although the results suggest that patients who were randomised to the tight glycaemic control group spent significantly less time in CCU/ICU (p < 0.00001), the significant heterogeneity (99%) of this sample makes it difficult to interpret these results. The data are significantly weighted by one study, the Lazar (2004) study, and the times spent in CCU/ICU vary dramatically between groups.
