Kidney Functions: Clinical and Epidemiological

Contains kidney care oriented functions. Current version contains functions for calculation of: - Kidney Donor Risk Index and Kidney Donor Profile Index for kidney transplant donors by Rao et al. (2009) . - Estimated glomerular filtration rate by CKD-EPI, MDRD and other equations. Citation: Bikbov B. R open source programming code for calculation of the Kidney Donor Profile Index and Kidney Donor Risk Index. Kidney Diseases (2018) 4:269–272 (the only citation for the whole package).

This is the source code for the "kidney.epi" package in R. It gets posted to the comprehensive R archive (CRAN) at intervals, each such posting preceded a throrough test. In general, each new push to CRAN with new function(s) will update the second term of the version number, e.g. 1.2.0 to 1.3.0. Updates only to the code of existing functions increment the third term of the version number, e.g. 1.2.0 to 1.2.1.

Internal datafarames

Internal datafarames are contained in the R/sysdata.rda of the source code, used in the R package functions but not accessible to the user.
Current internal datafarames:
ktx.kdpi_mapping_table - contains data with mapping KDPI and KDRI reported by OPTN for the years 2015-2016
ktx.kdpi_coefficients - contains data with coefficients used by OPTN for the calculation (KDRI scaling factor, chances of hypertension and diabetes in case if they were unknown for donor, etc)

External datafarames

ktx - contains data for 10 kidney transplant patients.
