A higher citH3 content is associated with the presence of cfTNP in EC sera. Box plots showing citH3 (A), cfDNA (B), cfmtDNA (C) levels in the two subgroups of EC serum samples that present cfMNP or cfTNP respectively. The upper border of the box indicates the upper quartile (75th percentile) while the lower border indicates the lower quartile (25th percentile), and the horizontal line in the box the median. P values (Mann–Whitney non-parametric test), n: 19 cfMNP and 25 cfTNP
