Summary of the linear regression analysis of eq. 17
CSF/Cu,p values were taken from reference (Caruso et al., 2013). Only compounds from (Caruso et al., 2013) for which 
and 
were available to calculate AP-ER were selected. Primary data are available in the Supplemental Information.
| Parameter | a (±S.E.) | b (±S.E.) | r2 | n |
|---|---|---|---|---|
| ER | 0.89 ± 0.10 | 0.14 ± 0.05 | 0.71 | 34 |
| AP-ER | 1.04 ± 0.10 | −0.03 ± 0.06 | 0.76 | 34 |
a and b are regression coefficients. Papp (+I), apparent permeability in the presence of an inhibitor.
