Fig. 4

Change in the nonsynonymous mutation over synonymous mutation ratio against gene expression breadth. We show data from both European (CEU) and Yoruba (YRI) populations surveyed, separated by sex. Blue line denotes the slope of the line under a linear model, while the gray shade denotes the 95% confidence interval from the univariate regression model. Beta and P value denotes beta coefficient between gene expression breadth and dN/dS in the univariate analysis, and the corresponding P value
