A significant Spearman correlation (⍴ = 0.52, adjusted P = 0.00041) was observed in myeloid cells, but not in CD4+ T or NK cells, suggesting that LOY and CH tend to co-occur in granulocytes and monocytes, and LOY may be the primary driver of CH in myeloid lineage. This evidence concerns the gene CD4 and cyclic hematopoiesis.
