Research on only one treatment is rigorous enough to earn an A grade

Parents who research treatments for autism are confronted with a bewildering array of options, almost all of which have never been tested for safety and effectiveness. Organizations like The Cochrane Collaboration, which reviews the quality of evidence for medical treatments, are putting more effort into evaluating popular alternative treatments.
So far, the most comprehensive review of alternative autism treatments comes from two pediatricians: Susan Hyman of the University of Rochester School of Medicine Golisano Children's Hospital at Strong and Susan Levy, a clinical professor of pediatrics at the University of Pennsylvania School of Medicine and The Children's Hospital of Philadelphia. Their 2008 analysis gave each treatment a letter grade for the quality of the research conducted up to that point; the mark, however, is not a ranking of the treatment's safety or effectiveness.
