Sir can you plz clear my confusion..In the two examples which you mentioned above of retrospective cohort , what can we take as non exposed group? 1) people who were present and witnessed the tragedy OR 2) people who weren't and still have the same dz. or problems as the exposed groups? Thanks.

Actually there was ideally another group present in the factory the same day. They were in another hall or room when the chemicals burned. Those people could be considered as un-exposed

I came to ask the same thing. About an example of the unexposed. In the example of 9/11, what would be the unexposed group? People living in another city of New York who were a little removed? Or someone in a completely different state?
