Relation between cyclin D1 and clinico-pathological features. a Pathological types (DCI vs IDC) at Z=3 (P=0.003). b Clinical stages (stage I to IV) at X2=9 (P=0.019). c Histological grading (grade I to III) at X2=6.9 (P=0.03). Statistical analysis was done using the non-parametric test; as for two variables, the Mann-Whitney U test (Z-value) was used; and for more than two variables, the Kruskal-Wallis H test (X2 test) was used
