Measure of reliability. Ten cases (and two cases for stereology) were re-analysed using all methods. (A) Table showing Pearson’s correlation coefficient (r), intraclass correlation coefficients (ICC) with 95% confidence interval (CI), ANOVA, and non-parametric P values for all methods. The 95% level of agreement’s upper and lower boundary values (UB, LB) in Bland and Altman plots were also presented. (B) Graphs showing the correlation (left) and Bland & Altman plots (right) of WMN density values between test and retest using all methods. (C) Table showing the time spent on each method. *see Eriksson et al. .
