*When is a level 2 scientific study NOT a level 2 scientific study?*
Answer: When it is a retrospective review of an insurance company database.
A recently published 2021 study by Dr. James Pritchett, is titled “The debit side of stem-cell joint injections: a prospective cohort study” and is listed as a Level 2 study by the journal…Current Orthopedic Practice.
However, not only was this study NOT prospective…it was also NOT a cohort study. What was it? It was a retrospective review of insurance company stem cell data (!) from 2012-2015. This is just one of about 10 problems with this “scientific paper”
