Among older community-dwelling adults, poorer performance on the Short Physical Performance Battery, a set of balance, walking and chair-rise tests, was associated with higher mortality and nursing-home admission after adjustment for other factors. This was observational prediction, not a treatment comparison. It does not show that raising a person’s test score will prevent either outcome.
Boundary: Residual confounding and limited transportability; no clinically validated surrogate or treatment-guidance utility shown.
