WebBland-Altman plots generally show the arithmetic mean of the two measures (x-axis) against the arithmetic difference of the two measures (y-axis). However, given the log-normal distribution of uncorrected and corrected urinary MnBP concentrations, we took the anti-log of measurement differences and means, resulting in Bland-Altman plots with ... WebThe Bland-Altman method calculates the mean difference between two methods of measurement with 99% limits of agreement as the common mean difference (3SD) or more precisely (2.575 SD). It is estimated that the 99% limits include 99% of differences between the two measurement methods. The Bland-Altman plots show the driving over the prescribed limit offence
