In contrast to the relationship we observed between the transcript level of IFNG-AS1 and the proportion of Th1 cells, there was no correlation between the transcript level of IFNG-AS1 and the proportion of CD8+ IFN-γ+ T cells (Supplemental Fig. 1A), which was significantly greater in HT patients than in healthy controls (Supplemental Fig. 1B). Here, IFNG is linked to hematocrit.
