Calculate the eGFR with the MDRD formula in EDC/CDMS
With this formula you can calculate the glomerular filtration rate (GFR) using the MDRD study equation:
var age = getDateDiff('{DOV}','{DOB}','y');
var eGFR= 186 * Math.pow(({creatinine}/88.4),-1.154) * Math.pow(age,-0.203);
if({sex} == 0) { eGFR = eGFR * 0.742; };
eGFR;
In this formula the following variables are used:
- DOV = date of visit
- DOB = date of birth
- Sex = sex
- Creat = creatinine
