Mean change in number of positive cells versus the difference in change in positive cells. Shown are scatter plots of the mean change in the number of positive cells versus the difference in change of positive cells between two measurements by observer 1 for (a) CD3⁺ lymphocytes, (b) CD38⁺ plasma cells and (c) CD68⁺ macrophages. The dotted line represents the mean ± 2 × standard deviation.
