Have you actually read the metamed sample reports/what do you think metamed actually does? As far as I can tell, their core product is to have a team of medical and phd students do a literature search for about 1 working day (compare to Up-to-date, where actual researchers in various fields write the reports and clinicians edit the treatment plans). This seems highly unlikely to move that 17 year lag even a little bit.

I have no horse in this race, but I have worked as a statistician for hospital researchers and for health insurance companies. I just happen to think metamed's boosters here are dramatically underestimating the availability of evidence-based-medicine literature surveys in the clinical hospital setting.
