On the data card and in the data, many abstracts are repeated on articles that don't match the abstract. Chasing the citation reveals the abstracts are propagated incorrectly. Titles and authors appear to still be ok on those articles, just not the abstracts.

As an example, look for this in the first few dozen rows of the train dataset card:
"Calcium carbonate appears to be as effective as aluminum hydroxide in binding dietary phosphorus in hemodialysis patients. The long-term safety of this medication appears acceptable in view of today's therapeutic options."

You'll see it appears with many articles that just don't match it.
