I think it is now mandatory to check all references if there any PubPeer notes or if the references even has been retracted.
A recent Nature News highlights the issue
Most of the papers that cite discredited COVID research in The Lancet and The New England Journal of Medicine don’t mention that the studies have been retracted. The infamous studies relied on health-record analyses from a company, Surgisphere, that declined to share its raw data for an audit. Science looked at 200 academic articles that cite the Surgisphere papers and found that 52.5% — including some in prominent journals — failed to mention the retractions.
