Table 4 shows multiple-dimensional comparisons between the mean ranks of each of the two groups of the three groups separately in each of the measurements, and the following is evident from it: For PT-, there are significant differences between the (G6PD) and (COVID-19) groups in the direction of the (G6PD) group, and there are no significant differences in the rest of the bilateral comparisons. This evidence concerns the gene G6PD and COVID-19.
