Statistical significance was analyzed using Spearman's rank correlation test. Correlation analysis was performed using combined data from both sexes in Pre (6, 7, or 8W), Pair_8W, and Single_8W. PC, positive correlation; NC, negative correlation; TNC, trend toward a negative correlation (0.05<P<0.1); ns, no significance (no correlation).
