Systematic reviews cited retracted articles, new study finds
A new study found some systematic reviews included retracted studies from paper mills, journals that produce low quality research

Systematic reviews, which involve pooling data from multiple studies and analyzing them together, are increasingly popular as a way to produce more authoritative conclusions than can be derived from the individual smaller papers. In recent weeks, systematic reviews have been used to justify policy around gender affirming care as well as in the MAHA report.
But, a new paper adds to a body of evidence that not all systematic reviews are created equal, at a time when some researchers are trying to think through alternatives to the current way of doing these analyses. The study, published in JAMA Network Open on Thursday, found a small number of systematic reviews included retracted studies from paper mills, journals that produce low-quality research to help researchers game the academic job market.
