highly significantp < 0.001
The assessment of the global similarities of the properties of mAPs between normalized groups using the χ 2 test (7 degrees of freedom) showed highly significant differences for all the analyzed pairs, i.e., P1P2N1/P1N1 ( χ 2 = 182.56, p < 0.001), P1P2N1/N1P1N2 ( χ 2 = 20.98, p < 0.01), P1P2N1/P1N1P2 ( χ 2 = 27.70, p < 0.01), P1N1/N1P1N2 ( χ 2 = 105.40, p < 0.001), P1N1/P1N1P2 ( χ 2 = 154.23, p < 0.001), and N1P1N2/P1N1P2 ( χ 2 = 21.04, p < 0.01).
