Pereira and coauthors assessed the frequency, features, and credibility of very large treatment effects in an evaluation of 85 002 forest plots in 3082 review articles. In an Editorial, Oxman discusses implications for clinical research and patient health.
As both hyperglycemia and hypoglycemia may adversely affect the developing brain, Mesotten and coauthors studied whether long-term follow-up was required to exclude harm and validated short-term benefits of tight glucose control in a large randomized controlled trial of 700 children. See the related Editorial by Tasker.
