Relationship between megakaryocyte subtypes and mutational status. Distribution of megakaryocytic phenotypes with respect to underlying mutational status. Difference between groups was tested using a Kruskal-Wallis test adjusted for false discovery rate using the Benjamini-Hochberg procedure. (A) Results with P < .05 were considered statistically significant and are indicated by an asterisk. Pairwise difference between mutational groups was tested using a Wilcoxon rank-sum test adjusted for false discovery rate using the Benjamini-Hochberg procedure. (B-I) Results with P < .05 were considered statistically significant.
