Note: Individuals were categorized into subsamples at the median for YBC-ED and EDE-G, and categorized into Yes/No for ANBP. Two sample t-tests were conducted to compare the subsamples in terms of various background variables (p-values corresponding to these tests are summarized as follow:
1
p < .05,
2
p < .01,
3
p < .001).
