'How long have i got doctor?' The development and validation of a new prognostic model

Abstract

In the current issue of Kidney International, Floege et al report the development and external validation of a prognostic score for patients starting haemodialysis. The model performs well and appears robust in various sub-groups and in external validation. This commentary takes a systematic approach to considering the generalisability of the results and applicability of the prognostic score to wider clinical practice.
