marginally significantP = 0.07
Coexpressed genes showed marginally significant evidence ( P = 0.07) of coevolution of the lengths of intergenic regions, but the extent of coevolution for intergenic lengths was significantly less than for intron lengths (e.g., partial Pearson correlation coefficients of genes belonging to the same GTEx coexpression clusters were significantly higher in the case of introns than intergenic regions; P = 7.4 × 10 − 8 ).
