<p>After exclusion of 17 lncRNAs for invalid primers and 7 lncRNAs for very low relative lncRNAs expressions, the expression differences between the varicose GSVs and control veins of 15 lncRNAs were measured by Q-RT-PCR. ΔΔCT show the actual relative expression fold change as 2<sup>-ΔΔCT</sup>. The positive value means down-regulated expression of the lncRNA between the varicose GSVs and control veins, conversely, the negative value means up-regulated expression of the lncRNA between the varicose GSVs and control veins. *: P<0.05.</p
