From: Increased CSF tau level is correlated with decreased lamina cribrosa thickness
Scatterplots showing the relationship between the cerebrospinal fluid level of total tau (T-tau) protein and the lamina cribrosa thickness (LCT). a Linear regression (dotted line) and fractional polynomial (FP) analysis (solid line) performed across all subjects. b Regression analysis with an indicator was performed using the diagnostic group (healthy vs. Alzheimer’s disease (AD) groups) as an indicator
