This web app is a decision tool that helps aid kidney acceptance/rejection decision for a diseased donor kidney offer. It uses the methodology described in [cite paper] to give an estimate of the survival times if the offered kidney is accepted, or if it is rejected. An estimate of the benefit with desired level of statistical significance is also provided. The tool requires patient, donor and transplant center characteristics in its survival estimation model. The survival estimation model used in this tool is described in [cite paper].
