ABCB1 mRNA levels in morphologically non-affected and affected tissues normalised to the β-actin mRNA level.

NS = not significant.ap-value for the comparison to the expression levels in tissue from healthy individuals using Kruskal Wallis and Dunńs Multiple Comparison test.bp-value for the comparison of the expression levels in normal and affected tissue from the same individual using Paired Student’s t-test.

NS 代表无统计学显著性。标注为a的p值：采用克鲁斯卡尔-沃利斯（Kruskal-Wallis）检验与邓恩多重比较（Dunn's Multiple Comparison Test），对比健康个体组织的表达水平所计算得到的p值。标注为b的p值：采用配对Student t检验，对比同一受试者正常组织与病变组织的表达水平所计算得到的p值。
