WitrynaFor example, log2 fold change of 1.5 for a specific gene in the “WT vs KO comparison” means that the expression of that gene is increased in WT relative to KO by a multiplicative factor of 2^1.5 ≈ 2.82. P-value: Indicates whether the gene analysed is likely to be differentially expressed in that comparison.
