Bland-Altman plots comparing the quality of recovery in Rhesus macaques receiving ketamine (n = 8) or fentanyl-midazolam-medetomidine (n = 8). The differences between the scores for each method are plotted against the mean of the two methods. (b) = bias; (b + 1.96 s; b – 1.96 s) = Agreement limits. The shaded lines represent the 95 % confidence intervals of the agreement limits
