Fig. 3From: Cerebrospinal fluid biomarkers that reflect clinical symptoms in idiopathic normal pressure hydrocephalus patientsCorrelation of Mini Mental State Examination outcome and biomarkers. Graphs of preoperatively obtained lumbar CSF biomarkers of T-tau (A), NfL (B) and Aβ42 (C) correlated with MMSE outcomes (T-tau r = − 0.18, NfL r = − 0.17, Aβ42 r = 0.18). Negative outcome is presented as a decrease in X-axis. Significant results are highlighted with asterisk (*p < 0.05). Linear trendlines are drawn to visualize the correlations. T-tau: total tau protein; NfL: neurofilament-light; Aβ42: Amyloid-β 42; MMSE: mini mental state examinationBack to article page
