The Dunn’s multiple comparison post hoc test with Bonferroni adjustment of p-values revealed a significantly higher CD45 expression in PVL group compared with OL group (p-adjusted = 0.0211) while no significant differences were found between PVL and PVL-OSCC groups (p-adjusted = 0.7036, Table S3), as well as between OL and PVL-OSCC groups (p-adjusted = 0.3307, Table S3). Here, PTPRC is linked to periventricular leukomalacia.
