The Journal of the American Medical Association reclaimed its place as the top medical/surgical journal by ad revenue—despite ad pages being down 14% for the first half of 2007 over the same period for 2006.

Last year’s usurper, the New England Journal of Medicine, saw ad pages down 25% for 2007, according to PERQ/HCI.

In an ugly year for primary care journals, all of the top five publications in the space saw double-digit losses. The list was rounded out by American Family Physician (down 24%), Medical Economics (down 13%) and American Medical News (down 28%).
