From: Parasagittal dural space and cerebrospinal fluid (CSF) flow across the lifespan in healthy adults
Analysis of relationship between anterograde and retrograde cerebrospinal fluid (CSF) flow in the cerebral aqueduct and CSF, gray matter (GM), white matter (WM), and parasagittal dural (PSD) volumes. The correlation analysis of WM and GM are non-significant. CSF volumes are negatively correlated with retrograde CSF flow (p-value = 0.04, q-value = 0.08). PSD volume correlate with both anterograde and retrograde CSF flow (p-values = 0.01 and 0.001, q-values = 0.04, 0.004). Gray area corresponds to 95 percent confidence intervals estimated using the Wald method. Relationships that do not reach the significant threshold after multiple comparison correction appear in light gray shade; significant relationships are denoted with an asterisk and with confidence intervals appearing in dark gray shade
