  • a Measure of the significance of a possible relationship between x and y values. In this case, x is the log of the ratio of IC50 values for the reference antagonist in the presence and absence of test antagonist (abscissae as for Fig. 11) and y is the log of the ratio of B0 values in the presence and absence of test antagonist (ordinates as for Fig. 11). See Materials and Methods for further details.

  • b Slope of the regression of x and y as shown in Fig. 11.
