The application of a chi-square test indicated that there was a statistically significant association between the presence of the CD4 marker and DWI (tumor margin infiltration), χ2 = 5.682, p = 0.017, and the phi and Cramer’s V coefficients (−0.287) revealed that the connection between the two variables was indirect and of weak intensity (p = 0.017). Here, CD4 is linked to neoplasm.
