What we make of it
Single small study (n=45) with unclear methodology. The study-type label 'cohort_study' is likely inaccurate — the cited paper appears to be a pilot interventional or open-label single-arm study, not a prospective observational cohort. No large independent RCTs have confirmed EPO for acne vulgaris. The mechanism claim that EPO 'balances hormonal fluctuations' is speculative and was not directly measured in the cited study.
