Bland–Altman plot depicting the comparison between cerebrospinal fluid lactate measurements with the standard method and those with the blood gas analyzer by relating the difference between each pair of values to their mean. The dotted lines indicate the range of 1.96 times the standard deviation from the mean of the differences. Aside of 10 marginal, there is only one clear outlier (in the lower right part of the diagram) not within the reference interval of the diagram
