CD34 and neoplasm: The application of a chi-square test indicated that there was a statistically significant association between the presence of the CD34 marker and DWI (tumor margin infiltration), χ2 = 9.743, p = 0.002, and the phi and Cramer’s V coefficients (−0.376) revealed that the connection between the two variables was indirect and of moderate intensity (p = 0.002).
