Regression equation and residual SD for each PET method
| Structure (method of analysis) | r | Regression equation | Residual SD |
|---|---|---|---|
| Mean putamen (Ki) | −0.604-150 | y = 0.0076 + 0.000075 x | 0.0017 |
| Mean caudate (Ki) | −0.53† | y = 0.0105 + 0.000049 x | 0.0013 |
| Mean total striatum (Ki) | −0.544-150 | y = 0.0066 + 0.000041 x | 0.0011 |
| Mean putamen (ratio) | −0.58† | y = 2.09 + 0.011 x | 0.272 |
| Mean caudate (ratio) | −0.50† | y = 2.32 + 0.008 x | 0.239 |
↵4-150 p < 0.0005; † p < 0.005 (Pearson product-moment correlation).
