PB and BM parameters according to the presence of CH or absence of CH (NCH). (A) Six PB parameters are shown in the boxplot. Horizontal dashed lines indicate usual values. For parameters impacted by sex, values for women are in red and values for men are in blue. (B) Percentages of BM cells from the erythroid lineage (left panel) and maturation of the erythroid lineage (right panel) in the BM of volunteers with CH or without CH (NCH) are shown in boxplots. (C) Percentages of BM cells from the granulocytic lineage (left panel) and maturation of the granulocytic lineage (right panel) in the BM of volunteers with or without CH are shown in boxplots. baso-E, basophilic erythroblasts; F, female; M, male; Mb, myeloblasts; MCV, mean corpuscular volume; Mm, metamyelocytes; My, myelocytes; ortho-E, orthochromatic erythroblasts; Pm, promyelocytes; poly-E, polychromatic erythroblasts; pro-E, proerythroblasts.
