Fig. 4.
Remifentanil effects on miosis. Measured remifentanil concentrations are presented on a log scale. Black circles represent non–obstructive sleep apnea patients and red triangles represent obstructive sleep apnea patients. The sigmoid inhibitory - EMax logistic function is plotted as a solid line for non–obstructive sleep apnea patients and a dashed line for non–obstructive sleep apnea patients. Values below the lower limit of quantification are not shown. 95% confidence bands for each group are also plotted (grey for non–obstructive sleep apnea and red for obstructive sleep apnea).
