At the bottom lines, p-values and chi-square test statistics correspond to the homogeneity tests comparing the "Cases Before Surgery" to "Controls". The results obtained for the homogeneity test comparing "Cases After Surgery" versus "Controls" are also reported in the tables, although this does not contribute to the sensibility/specificity analysis.
