CSF vs serum sPLA2 activity.a
| Healthy individuals (n = 10) |
|
|---|---|
| Sex, F/M | 3/7 |
| Age, years | 53.0 (22.6) |
| CSF/serum sPLA2 activity ratiob | 0.4 (0.1) |
| CSF/serum protein ratioc | 0.013 (0.003) |
a
Categorical data (sex) and continuous variables (age, CSF/serum sPLA2 activity ratio, CSF/serum protein ratio) are expressed as number of individuals and as mean (SD), respectively.
b
Whereas CSFs were undiluted, sera were appropriately diluted to get similar protein concentration between CSF and serum-matched samples.
c
Protein concentrations were measured using bicinchoninic acid protein assay (Pierce).
