## Resource

This week, primary care physicians Kate Rowland, Mark Ebell, and Henry Barry want to arm our primary care colleagues with the best evidence on whether acetaminophen causes autism, whether MMR causes autism, and whether leucovorin can treat autism. Gary then turns to a study of the value of continuity in primary care, and its association with better health outcomes.
