CLAIM CARD
Within this outcome class, the evidence is broadly convergent: all studies agree that HGS correlates with relevant physiologic parameters. However, a notable tension exists between the null-to-positive signal reported by most studies (Lee 2026; Najjar 2026; Yldz 2026; Ji 2026; Urbano 2026) and the negative age-related trajectory documented by Chan 2022. This tension—between HGS as a modifiable, responsive marker (Yldz 2026) and HGS as a trajectory-bound biomarker of aging (Chan 2022)—remains unresolved and has implications for intervention design.
