Help needed with the eGFR MDRD Formula

sanchezpeinado — Sun, 11 Jun 2023 11:49:56 GMT

Hi all, I need help creating the following formula: eGFR = 175 x (SCr)-1.154 x (age)-0.203 x 0.742 [if female] x 1.212 [if Black]

thanks

Hopefully this example will give you a clue:

// = 175 x (SCr)-1.154 x (age)-0.203 x 0.742 [if female] x 1.212 [if Black]

= 175*:SCr - 1.154*:age - 0.203*If( :sex == "female", 0.742, 1 )*If( :race == "Black", 1.212, 1 )

Thank you Mark,
Still not working, what am I doing wrong
175 * (:BL_lab_cr - 1.154) * (:age_BL - 0.203) * If( :gender_decode,"female" * 0.742,1) * If( :race_decode,"black" * 1.212,1)
