EZH2 and neoplasm: A high EZH2-score-III was associated with higher tumor-grading: G1 M = 3.31; SD = 1.80; 95% CI 2.58–4.04; G2 M = 4.74; SD = 1.83; 95% CI 4.31–5.17; G3 M = 5.15; SD = 1.74; 95% CI 4.42–5.93 (Kruskal-Wallis-test, p = 0.001; Likelihood ratio, p = 0.041; crosstab analysis linear-by-linear association, p = 0.001).
