Fig. 4From: Detection of in vivo mutagenicity in rat liver samples using error-corrected sequencing techniquesThe mutation frequency of A:T > T:A in the non-treated control and DEN-treated group samples (blue and orange bars, respectively). The Y-axis indicates the A:T > T:A mutation frequency in a 10−6 order in each sample. * indicates p < 0.05Back to article page
