The example paper does not mention what type of diabetes it is about - if type 1 or type 2 - and they have very different risk factors.

While it’s kind of clear form the context that it’s about type 2, I doubt a paper like this would pass a peer review without stating it explicitly, in particular with respect to the data set that could potentially include both. Rigor is essential in drawing scientific conclusions.

I guess this is a good example about the statistical nature of LLMs outputs (type 2 is the most common) and consequentially their limitations...
