  1. r – correlation coefficient
  2. 95% CI – rho is the 95% confidence interval around r calculated using Fisher's transform
  3. p-value – value for testing the hypothesis of no correlation against the alternative that there is a non-zero correlation
  4. n – number of genes in each pairing used in correlation calculation
