Eleven further ads from recent issues of other journals were investigated likewise. The 14 issues contained 95 different full drug ads, each being repeated 4 times on average. About half cited one reference or more. Eighteen of the ads referred to unidentified documents, the others gave a code number or indicated the nature of the document. Initial responses to 19 of the 38 requests were received within 10 days.
Many claims thus seem inadequately supported.
Standards and remedies are needed.
