Evidence grade
G_EVIDENCE_GRADEWhat does this word mean?
The strength-of-evidence label the site attaches to every claim, ranging from human RCT through human observational, animal, cell and in vitro, review, correction notice and retraction.
Expanded note
In vitro and animal studies are never presented as clinical efficacy, and every efficacy statement carries an explicit evidence grade rather than standing as a bare claim.
Not a generic example.
The 60 entries in the site research library include 1 retraction and 4 correction notices, all retained in the library and explicitly flagged.

PDRN is not approved by the FDA for injection or any therapeutic use. Topical and injectable PDRN are parallel facts under different regulatory pathways and must not be directly equated.
PN is not PDRN. Evidence grades are labelled on every factual element; in vitro and animal research is never described as clinical efficacy.
