MAFTRR and hematocrit: Notably, we found that IFNG expression was positively correlated with MAFTRR expression (r = 0.3862; p = 0.0166) (Figure 2(d)), and a notable inverse correlation between IFNG transcripts levels and MAF transcripts levels was also found in PBMCs from the HT patients (r = −0.4234; p = 0.0081) (Figure 2(e)).
