To the Editor: The meta-analysis by Dr Soylemez Wiener and colleagues1 assessed the benefits and risk of tight glucose control in critically ill patients. In the Comment section, the authors discussed the quality of glucose control and found that 21% of the studies included did not achieve a mean glucose level within 5 mg/dL of the stated goal. This success rate presumably refers to the intensive treatment group only, although not stated explicitly.
