Comparison of Two Storage Methods for the Analysis of Cholinesterase Activities in Food Animals
Figure 5
Bland and Altman plot of the ratio of the storage at −80°C and −20°C (plotted on the -axis) versus the average of the storages (-axis) for food animal ChE activities. Horizontal lines are drawn at the mean difference, and at the mean difference ±1.96 SD of the differences (dashed line). If the differences within mean ±1.96 SD are not clinically important, the two storages may be used interchangeably for tissue samples.
