Note: Kruskal-Wallis test is used for comparison between groups. Mean rank multiple comparison of Kruskal-Wallis test is used for pairwise comparison. “, ” row: all subjects (including healthy subjects), Kruskal-Wallis test statistical analysis result. “(, )” row: excluding healthy subjects, Kruskal-Wallis test statistical analysis results between patients with different types of cancers and Kruskal-Wallis test statistical analysis results after excluding healthy subjects. Compared with the case of healthy control group, there is a statistical significant difference ().
