  1. aValues are means of either 3 (within group comparisons) or 4 (between group comparisons) correlation coefficients. Self-correlations (only occur in within groups comparisons) are not included to avoid bias
  2. bMeans followed by the same letter do not differ significantly (P < 0.05) by Tukey’s HSD test
