Number of significant tissue-specific (p < 1E-6) ortholog pairs with different strengths of association. r indicates the Pearson correlation coefficient for the A-C test p values for orthologs expressed in at least 3 normal tissues in common in human and mouse and expressed in at least one human tissue and one mouse tissue with p < 1E-6.
