- The table shows the linear mixed model analyses, including the fixed effects, the random effects, and the ICC of the FSS-3, FSS-9, VAFS, and the single items of the FSS-9. The random effects show the residual, the slope, and the covariance between the intercept and slope
- Covi,s, Covariance between intercept and slope; ICC: Intraclass Correlation Coefficient of between on total variance; I: Intercept (baseline); S: Slope (change); σ2: variance (residual, intercept and slope); σ2i,s: Covariance between intercept and slope
- *P < 0.05; **P < 0.01; ***P < 0.001
- aFSS-9: Nine-item Fatigue Severity Scale
- bFSS-3: Three-item Fatigue Severity Scale
- svItems included in the FSS-3
