Frailty alone predicted IADL disability (sHR 1.70), ADL disability (1.54), falls (1.60) and severe mobility limitation (1.92). Coexistent frailty+sarcopenia predicted IADL disability (1.58), while sarcopenia alone was not significantly associated with measured outcomes.
Observational; Korean cohort may limit transportability; subgroup sizes for combined frailty+sarcopenia may reduce precision; surprising absence of association for some combined-group outcomes warrants cautious interpretation.

Frailty assessment may identify future functional vulnerability better than sarcopenia classification alone. This supports keeping frailty and function central in assessment rather than assuming muscle diagnosis captures the whole risk picture.
