Appraisal of an article on prognosis

Royal Free Hospital School of Medicine, Rowland Hill Street, London NW3 2QG

^* Correspondence

Although problems with the validity and generalisability of the study were identified, this article yielded useful information. We conclude that it is not possible to address all clinical questions using the evidence-based framework.
