VP localization agreement. Bland–Altman difference plots show distances from apex to VP center on stress (red) and rest (blue) images, with VP positions from expert 1, expert 2, average positions from experts [experts = (expert 1 + expert 2)/2], and automatic VP localization procedure (SVM). 95% CIs for SVM vs. experts were narrower for AC stress and rest images (P < 0.01) and the same for non-AC stress and rest images (P = NS) as compared with 95% CIs for expert 2 vs. expert 1.
