Neurofilament light chain levels were not related to neuropathic-like pain There were no significant differences in serum NfL levels in participants dichotomized into neuropathic and unlikely neuropathic pain across cohorts using absolute NfL concentrations ( P = 0.11) and a nonsignificant trend in NfL z-scores ( P = 0.08, Fig. 3 ).
