Original Question

How could this discussion post be responded to? “I think discrepancies between observational studies and randomized trials happen because of how different the study designs really are. Observational studies can show an association, but they don’t control for all the outside factors that might influence the final outcome. For example, with beta carotene, people who were taking supplements might also have had other healthy habits that affected the results. So it looked like beta carotene helped, but in reality, it might not have been the beta carotene at all. Randomized controlled trials, on the other hand, are designed to limit those outside influences by randomly assigning people to groups. That’s why when they tested beta carotene in the CARET trial, the results were totally different and actually showed harm. After taking this course, I feel like I understand public health issues a lot better. I didn’t always think about how strong the evidence was, however, now I can look at studies more critically and understand what measures like incidence or risk ratios actually mean. It’s definitely made me more aware of how important good study design is when it comes to making public health decisions.”
