  1. * Significant correlation / difference at p < 0.05
  2. 1 Pearson correlation coefficient (r) or its estimated value from Kendall Tau rank coefficient (re) are presented. Positive correlation value denotes an increase in Fdiff with the increase in the factor value
  3. 2 Positive T-test value denotes greater Fdiff in females
