Fig. 1From: Effect of baseline cognitive impairment on association between predicted propofol effect site concentration and Bispectral index or sedation scoreBland-Altman plots. a shows Bland-Altman plot for OAA/S and Ce. Y-axis is calculated difference between OAA/S and Ce; X-axis is mean of OAA/S and Ce. OAA/S values were reversed in order (i.e., 5 – OAA/S was used). OAA/S and Ce values were then standardized to have respective distributions both with mean of 0 and standard deviation of 1. b shows Bland-Altman plot for BIS number and Ce. Y-axis is calculated difference between BIS number and Ce; X-axis is mean of BIS number and Ce. BIS values were reversed in order (i.e., 100 – BIS was used). BIS and Ce values were then standardized to have respective distributions both with mean of 0 and standard deviation of 1Back to article page
