From: Neurological affection and serum neurofilament light chain in wild type transthyretin amyloidosis
Comparison of serum NFL levels in patients with A-ATTRwt with different severity of neuropathy. (A) Boxplots comparing serum neurofilament light chain (sNFL) age and BMI adapted levels (z-scores) as described by Benkert et al.19 of patients with NIS < 20 and NIS ≥ 20. Statistics: unpaired t-test; p = 0.010; NIS < 20: n = 41; NIS ≥ 20: n = 11. (B) Boxplots comparing sNFL z-scores of patients with spinal canal stenosis (SCS) and without SCS. Statistics: unpaired t-test; p = 0.526; SCS: n = 13, no SCS: n = 30.
