Studies about finasteride effectiveness based on race/ethnicity?

[Selb]

I’ve been looking for these studies since I’ve heard that Asians typically see the best results, but I’m having no luck.

Ideally it would be a finasteride effectiveness analysis based on the following races/ethnicities:

North European
Southern European/Mediterranean
Slavic
African
South Eastern Asian
North Eastern Asian
Middle Eastern
North African
Hispanic/Latino
Native American

Maybe we can do it ourselves with a survey/poll
