Table 1 Diagnostic accuracy of the proposed CAD system. Feature selection had a significant impact on classifier performance with Friedman test \(\chi ^2 = 32.7\), 3 d.f., \(p = 3\times 10^{-7}\). V: Wilcoxon signed rank statistic of performance compared to complete system; p: Associated Bonferroni-corrected p-value.
