Because we are observing new cases of disease in a cohort study, what kind of relationship may we establish? Group of answer choices Confounding Temporal Positive Negative Why might there be uncertainty with the association between an exposure and disease in an observational study? Group of answer choices The association may be due to the factors that led people to be exposed (e.g. confounders) rather than the exposure itself. Case-control studies are more valid, so they should be the standard...
