The Dunn’s multiple comparison post hoc test with Bonferroni adjustment of p-values showed a significantly lower GATA3 expression in PVL-OSCC group compared with PVL (p-adjusted = 0.0493) or with OL group (p-adjusted < 0.001), while no significant difference was observed between PVL and OL groups (p-adjusted = 0.5442, Table S3). This evidence concerns the gene GATA3 and periventricular leukomalacia.
