Comparison of KATP channel modulators in different preparations
| Abscissa | Ordinate | r | Slope | d |
|---|---|---|---|---|
| Rat cardiac membranes | SUR2A | 0.98 | 0.98 ± 0.08 | −0.28 ± 0.07 |
| Rat aortic strips | SUR2B | 0.95 | 0.96 ± 0.12 | −0.27 ± 0.13 |
| SUR2B | SUR2A | 1.00 | 0.96 ± 0.04 | −0.55 ± 0.043-a |
Linear correlation analysis of the pKi values listed in Table 2 gave correlation coefficients (r), slopes (s), and mean distance (d) from line of identity as listed below. s = 1 means that Ki values on the two axes are proportional to one another and 10d gives factor by which, in mean, Ki values on ordinate differ from those on abscissa.
