Figure 5. The correlation between neostigmine Ce⁵⁰for foot analgesia and the concentration predicted by the post hoc Bayesian individual pharmacokinetics 5 min after a bolus of 1 [micro sign]g. Similar correlations between the magnitude of the predicted concentration after a unit bolus and the Ce⁵⁰for foot analgesia were seen at every time point from 1 min to 60 min after neostigmine.
