Adding Nf‐H and Nf‐L protein concentrations above the median to the multivariate prognostic model showed that higher levels of these analytes had a mild but significant effect on survival only for Nf‐H (HR: 1.728, CI: 1.026–2.909, p = 0.040), while Nf‐L protein concentration effect was only close to significance (HR: 1.921, CI: 0.986–4.056, p = 0.068; Fig. 4E and F ).
