Figure 3
From: Rapid and Precise Semi-Automatic Axon Quantification in Human Peripheral Nerves

shows a Bland-Altman plot plotting the differences between the semi-automated and manual method on the y-axis against the manual counts as goldstandard values on the x-axis. In this depiction an outlier is removed for format purposes (−3832 axon difference, manual count 1894). The mean difference of automated and manual counts is −147 (blue line). Thus, the automatic method produces higher counts than manual. The range within the 95% limits of agreement is high (red dotted lines). The difference between counting methods increases with increasing absolute axon count (black regression line).
