I'm not clear on what assumption you are claiming I made. My point was about quality of evidence (see, e.g., [1]). Observational studies are considered lower-quality evidence than randomized trials.

I see. I was under the impression that you were criticising this study in particular - apropos of assumptions.

Sorry.
