Fig. 1From: Plasma and cerebrospinal fluid neurofilament light concentrations reflect neuronal damage in systemic lupus ErythematosusCorrelations between NfL concentrations and age in SLE patients. a Increasing plasma NfL (log) correlates with increasing CSF NfL (log). r: 0.72. p < 0.001. b Increasing plasma NfL (log) correlates with increasing age. r: 0.52. p < 0.001. c Increasing CSF NfL (log) correlates with increasing age. r: 0.51. p = 0.003Back to article page
