¹The value was compared by Wilcoxon’s rank-sum test;

²The value was compared by Pearson χ² test;

³The value was compared by Pearson Kruskal-Wallis ANOVA test;

⁴The value was compared by Student's t-test. DLBCL: Diffuse large B cell lymphoma; MALT: Mucosa associated lymphoid tissue; THKmax: The maximal thickness.
