Assessment of functional status
Concepts
- PCFS Scale
"In both study phases, functional status was evaluated using the PCFS scale,12 which grades daily life limitations from 0 (no limitation) to 4 (severe limitation)."
- Primary Analysis
"For primary analyses, PCFS was dichotomized as none or negligible limitation (grades 0–1) vs at least slight functional limitation (grades ≥ 2), consistent with previous publications14,15. This thres
