Experts warn against retaining mpr at 14 reports

I apologize, but I'm not familiar with the term "MPR" or the context of "retaining MPR at 14 reports." Could you please provide more information or clarify what MPR stands for and what kind of reports you are referring to?

If you meant to say "experts warn against retaining MPR at 14 reports," I would like to know more about the context and what MPR stands for. Is it a medical term, a business term, or something else?
