Correlations between the frequency of CpG-island methylation and tumor stage or grade.

Note: Based on MSP data. 1-st CpG—promoter CpG-island; 2-nd CpG—intronic CpG-island; rs—Spearman’s rank correlation coefficient; P—p-value.
Correlations between the frequency of CpG-island methylation and tumor stage or grade.

注：本数据集基于MSP数据。第1个CpG为启动子CpG岛（CpG island）；第2个CpG为内含子CpG岛（CpG island）；rs为斯皮尔曼秩相关系数（Spearman’s rank correlation coefficient）；P为p值（p-value）。
