Impact of the EARL harmonization strategy on Dice and concordance indices between MATVs extracted from OSEM images and PSF images (observer 1). The PSF7 images were filtered to meet EARL requirements while PSF images were optimised for diagnostic potential. Data are shown as Tukey boxplots (lines displaying the median, 25th, and 75th percentiles; crosses represents the mean values). Dice coefficients and concordance indices are shown for both the isocontour-based method (a, b) and gradient-based method (c, d). ns not significant
