[Usefulness of Cochrane Collaboration for pediatric cardiology].

The Cochrane Collaboration provides growing and readily accessible resources to help ensure that medical decision-making is based on detailed, methodical, and up-to-date reviews of the best available evidence. We analyzed systematic reviews in the field of pediatric cardiology published by the Cochrane Collaboration's 50 Collaborative Review Groups. We found a total of 20 systematic reviews: 13 published by the Cochrane Neonatal Group, 6 by the Cochrane Heart Group, and 1 by the Cochrane Peripheral Vascular Disease Group.
