| name | Kidney failure 2-year risk [Likelihood] by KFRE | ||
| description | The two-year "treated kidney failure" risk as calculated by the Kidney Failure Risk Equation (KFRE), for patients with chronic kidney disease stages 3 to 5. "Treated kidney failure" is defined as kidney failure that is treated with either dialysis or kidney transplant. The KFRE includes the following variables: patient age, sex, estimated glomerular filtration rate (eGFR), and urinary albumin-creatinine ratio (ACR). In this model, all variables are time-independent, in that the baseline measurement is used for all calculations. [PMID: 26757465] | ||

| time | Pt = Point in time: To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements. | ||

| scale | Qn = Quantitative: The result of the test is a numeric value that relates to a continuous numeric scale. Reported either as an integer, a ratio, a real number, or a range. The test result value may optionally contain a relational operator from the set {<=, <, >, >=}. Valid values for a quantitative test are of the form "7", "-7", "7.4", "-7.4", "7.8912", "0.125", "<10", "<10.15", ">12000", 1-10, 1:256 | ||
