You should find some good references in the Bandolier's site (Diagnostic testing emerging from the gloom, Tuberculosis diagnosis, etc.). A rare metanalysis on diagnostic tests for UTIs is by Gorelick et al in Pediatrics 104 (5) page ?, 1999. Ebell et al use an LR-based clinical prediction rule for Strep Throat (JAMA 284,2912,2000). More examples in Black et al Diagnostic Strategies for common medical problems 2nd Ed 1999, ACP. A review on the physicians' testing practices in JAMA 1998, 280, 2020. Hope it helps. I'm strongly interested on this subject, too. Did you find anything else? Giuseppe At 16.22 23/01/01 +1300, you wrote: >I am trying to put together some reading for an EBP paper.
