    In this article, we review guidelines which may be used to evaluate studies documenting prognosis. We describe a clinical problem involving the prognosis of a patient in an intensive care unit. An approach to the literature search is then outlined. The results of the literature search are described and criteria for the appraisal of articles describing prognosis and prognostic factors are discussed using one article as an example.
