Fig. 2From: Different mutational characteristics of the subsets of EGFR-tyrosine kinase inhibitor sensitizing mutation-positive lung adenocarcinomaMutational pattern of study cohort. Box plot summarizing the SNV and box plot of Ti and Tv in the E19del-subgroup (a and b) and in the SNV-subgroup (c and d). Mutational signature plot derived from a 74 X 96 matrix analyzed using the NMF, where 74 is the number of the study cohort (e) and bar graph indicating the degree to which each case contributed to the signature (f). *n.s. not significant. ** P-value was obtained by Wilcoxon signed rank testBack to article page
