Glucose control in non-ICU; no right answer

This large meta-analysis evaluated the risks and benefits of intensive or liberal glucose control in non-ICU patients and found no difference for most outcomes (stroke, MI, death), a reduction in rates of infections (relative risk 0.44, CI 0.21 to 0.77), but an increase in rates of hypoglycemia (relative risk 1.58, CI 0.97 to 2.57). Intensive glucose control does not appear to substantially benefit non-ICU patients overall (abstract)
