Results of the meta-analysis conducted on the time spent on mechanical ventilation, following cardiac surgery, for patients with and without tight glycaemic control. This figure illustrates the forest plot created from the meta-analysis of the time spent on mechanical ventilation, following cardiac surgery, for patients with and without tight glycaemic control. The results of this analysis suggest that patients who experienced tight glycaemic control peri and/or post-operatively spent significantly less time on mechanical ventilation (p < 0.00001). However, the results are heavily weighted by the Lazar (2004) study due to the wide ranges of time and large standard deviations in the other four studies.
