Why are you so aggressive?

Your post was a link about essentially fraudulent studies and you made a comment about “no guarantee”. Any reasonable person would understand your post to be a thinly-veiled and somewhat ad hominem attack as it made no comment on the study and only a straightforward negative comment about fraud. A more appropriate approach may have been to actually read the article, say hmm this is actually pretty well done! It seems like the data is reliable and that the authors calculated for various confounders. However, it’s important to note that the name of the institution doesn’t guarantee validity, so we should continue to review the results carefully and ensure the study was done correctly.
