Fig 1. Comparisons of gene expression levels, tissue specificity in gene expression, and number of protein interactions between X-linked (X) and autosomal (A) genes.
The horizontal line inside each box indicates the median. The length of the box and the whiskers represent 50% and 90% confidence intervals, respectively. Asterisks indicate statistically significant differences (Mann-Whitney U test; P < 1×10-12 for expression levels, P = 1.6×10-4 for tissue specificity, and P = 3×10-4 for protein interactions).
