Discriminat validity of the PFS physical score – Spanish version with physical performance and physical activity measures.
| Measures | PFS Physical Score | ||||
|---|---|---|---|---|---|
| LS means (SE)a | Difference | AUC | |||
| Yes | No | Mean (SE) | 95%CI | ||
| Poor physical performance b | 23.5(1.0) | 15.6(1.2) | 7.9(0.3) | 7.3-8.5 | 0.77 |
| Slow gait speed c | 23.1(1.2) | 17.5(1.1) | 5.6(0.3) | 5.0-6.2 | 0.69 |
| Low strength performance d | 24.1(0.9) | 16.4(1.1) | 7.6 (0.3) | 7.0-8.2 | 0.79 |
| Low physical activity e | 23.1(1.1) | 20.2(1.7) | 3.1(0.3) | 2.5-3-7 | 0.64 |
LS means: Least squares means, SE: Standard Error, AUC: Area Under the Curve.
a
Adjusted by age and gender.
b
Defined as Short Physical Performance Battery (SPPB) <10 points.
c
Defined as low gait speed: gait speed ≤0.8 m/sec during a walk at usual pace over 4-meters.
d
Defined as time to performed chair stand test ≥16.7 seconds or not able to do 5 stands.
e
Defined as weekly walking time ≤2.5hours/week.
