Hi! I'm looking into a sex-related sub question of my bachelor's thesis about heart failure and oncomarkers. Even though male/female values do not seem significantly different at first glance, I would like to create the following:

I want to match a female patient to a male patient who have the same/similar age and same/similar lab values (creatinine and nt-proBNP). I would like to see their oncomarker values.

Thank you in advance!
