Hi!

I'm trying to use this formula to calculate eGFR: eGFR = 142*min(standardized Scr/K, 1)^α *max(standardized Scr/K, 1)^-1.200 *0.9938Age *1.012 [if female]
Scr= creatinine, e.g. creatinine=2.4.

In this formula, the min(standardized Scr/K, 1) means that you either choose the creatinine value divided by kappa, OR 1. The same goes for the max-one.

I'm looking for advice on how to write the command so Stata realizes this. Grateful for any help!
