Nephron Clin Pract. 2011;119(3):c255-60. doi: 10.1159/000328916. Epub 2011 Sep 14.


In contrast to the Kaplan-Meier method, Cox proportional hazards regression can provide an effect estimate by quantifying the difference in survival between patient groups and can adjust for confounding effects of other variables. The purpose of this article is to explain the basic concepts of the Cox regression method, and to provide some guidance regarding the presentation of the results.
