Confirmed by the original peer-reviewed Nature Medicine study (Xu et al. 2018) and corroborated by NIA press release and independent science journalism (STAT News, EurekAlert). Multiple independent sources consistent with no contradictions. [cascade flags: aggregator_dropped_primary_exists | tier=silver indep_score=1.0 clusters=2 claim_tier=notable]
