Figure 3. Frequency distribution bar diagram illustrating the nuclear expression levels of (a) karyopherin a2 (KPNA2) and (b) p53. KPNA2 and p53 expression were analyzed for nonparametric statistics as dichotomized variables with their respective median (5%-< 10% for both variables) being set as cut off value. Thus, low KPNA2 and low p53 expression were defined as expression levels < 5%
