Three horizontal lines exist in the plot, the mean bias () computed as. (8.12) and the limits of agreement computed as.
WebAdded in response to @Nick: Bland-Altman plots plot the difference between two measures against the average of the two measures, so to be meaningful the two measures need to be measured on the same scale. Converting two measures that are on different scales to dimensionless standardised scores allows you to do the necessary calculations. gohpt.comWebThe limits of agreement in the Bland-Altman plot were ± 19 mmHg; the mean values differed by 1 mmHg.
