highly significantp < 0.002
For these 21 miRNAs, all data from stage I and stage II were merged and analyzed together resulting in highly significant DEG that survived Bonferroni correction for multiple comparisons (p < 0.002 [0.05/21]) and ROC between 0.9–1.0 were calculated for most genes suggesting a complete or almost complete separation of gene expression relative to the pre-exposure reference (bold p-values, Supplement Table 2 , right part).
