“already naturally randomized”
Sorry. That’s not a thing .
“they all have various underlying medical conditions, all types”
says who? what are the conditions they have?
” and the control group are the ones who have not yet developed any underlying medical conditions as yet”
thats not a control group.
A control group is comparable to the studied group to see if there is a difference between the two.
You don’t seem to understand much about how studies are done, as your past few posts are full of very basic errors. you dont know what a control group is, you don’t understand randomization no0t to mention how studies avoid (Though not eliminate) chance.
I’d be happy to explain it to you. but you’d have to listen as I’m beginning to suspect you aren’t reading my posts since you are repeating lots of pints that have been addressed several times.
