The number of nonrelevant articles retrieved is expressed per relevant article and was rounded up to the nearest whole number. The search phrases as determined and typed in by physicians were: “(bleeding OR blood) AND (platelet OR antiplatelet) AND end stage renal disease,” “hemodialysis AND surveillance AND (fistulae OR graft),” “intradialytic AND L-carnitine,” “(homocysteine AND end-stage renal disease,” “thrombosis AND platelet AND hemodialysis access.” Renal dialysis terms were removed when the physician search was combined with dialysis search filter.
