I think this is the most clear explanation of confounding I have heard. Also an excellent example of why diabetes would likely not be a confounder in relation to obesity - CHD. Thank you!
So, in general, we adjust for confounders to make two groups comparable in all other way BUT the primary exposure? (can it be worded like this?). Secondly- lets say we take another variable - nicotine patch use. Lets say it satisfies the definition (3-criteria based) on confounding. But what if we do not have data about that at all?! What if the researchers did not collect any information regarding a certain potential confounder? What would we do in that case? Please let me know. Thanks

Great Epidemiologist, thanks so much
Wonderful lecture

Big help Professor 👍
Thank you very much. But why did not you upload the RCT or experimental study
He said "86%" but I think he meant 86 to mean the # of people in that category
Great video , thanks sir
