Correlation between f(HMA) values of albumin and age of 42 subjects (serum, open circles; CSF, open triangles). There is a significant negative correlation between age and f(HMA) value from the serum (R = −0.635, P < 0.0001), however, no correlation is observed between age and f(HMA) value from the CSF (R = 0.086, P = 0.59)
