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
