Some study entries may include more than one citation because each citation examines a different follow-up period from the same study sample, or because each citation examines a different set of outcome measures on the same study sample.

Information on study characteristics is available only for studies that received a high or moderate rating. Read the description of the review process for more information on how these programs are identified.
