  1. All values are described as median (minimum-maximum).
  2. P values in the rightmost column were calculated using Kruskal-Wallis tests.
  3. * p < 0.017 vs. controls, using a two-tailed Mann-Whitney U-test with Bonferroni correction.
  4. † p < 0.017 vs. AN-R, using a two-tailed Mann-Whitney U-test with Bonferroni correction.
  5. ‡ p < 0.017 vs. AN-BP, using a two-tailed Mann-Whitney U-test with Bonferroni correction.
  6. § p < 0.05 vs. AN-R, using a usual two-tailed Mann-Whitney U-test.
