EZH2 and neoplasm: A high EZH2-score-I corresponded statistically with a higher tumor-grading: G1 M = 4.85; SD = 2.34; 95% CI 3.90–5.79; G2 M = 7.00; SD = 2.98; 95% CI 6.30–7.70; G3 M = 7.26; SD = 2.54; 95% CI 6.16–8.36 (Kruskal-Wallis-test, p = 0.001; Likelihood ratio, p = 0.061; crosstab analysis linear-by-linear association, p = 0.003).
