Note: Values in bold, P < 0.05 (r ≥ 0.24); values in bold and italics, P < 0.001 (r ≥ 0.39). A negative correlation means that higher CSF concentrations are related to more brain atrophy (i.e. negative change in volume) and less ventricular expansion, and a positive correlation means that lower CSF concentrations are related to more atrophy and less ventricular expansion.
