The median κ-FLC index determined at baseline was numerically higher in progressive patients (43.7; 15.5–108.2) compared to the stable group (26.1; 13.9–75.8); however, this difference did not reach statistical significance (p = 0.328; Table 2 ). κ-FLC index does not predict disability progression in PPMS Multivariable Cox regression analysis showed that the κ-FLC index was not a statistically significant predictor of time to disability progression [hazard ratio (HR) 1.0, p = 0.950].
