PVT1 and hematocrit: The results manifested that HT incidence in the lncRNA-PVT1 low-expression group was 80.25%, which was higher than that in the lncRNA-PVT1 high-expression group (20.25%), and HT incidence in the miR-146a high-expression group was 80.92%, which was enhanced compared to the miR-146a low-expression group (22.62%) (all P < 0.05) (Table 4).
