Reduction in diameter, comparison between manual and semi-automatic detection (n = 24 data).

<p>On the left, the regression line between the two methods. Regression line has a slope of 0.869 and an intercept of 0.0388. Pearson r-value squared is r<sup>2</sup> = 0.9691. Sum of the squared errors is SSE = 0.021. On the right, the Bland-Altman plot. Reproducibility coefficient and % of mean values RPC (%) = 0.047 (9%); coefficient of variation CV = 4.6%. The solid line represents the mean of the differences; dotted lines define the interval mean difference ± 1.96 SD.</p>
