highly significantP <0.01
We found 10 genes (IL15, IL17A, EBI3, CCL3, CCL5, LTB, CSF2, IFNG, RANKl and NOS2) with highly significant differential expression ( P <0.01), 6 genes (IL2, IL8, IL10, TNF, TGFB1 and VEGFA) with significant differential expression ( P <0.05 but >0.01) and 5 genes (IL6, IL12A, CCL2, LTA) not correlated with the disease status according to Kruskal–Wallis ANOVA test ( Table 1 ).
