From: Epidermal growth factor alleviates the negative impact of urea on frozen-thawed bovine sperm, but the subsequent developmental competence is compromised

Figure 6

(A) Heatmap of pairwise correlations between variables. The Anderson–Darling test showed that data were normally distributed. Therefore, the Pearson correlation coefficient (as parametric correlation estimator) was used to assess the association between the two variables. The red and green boxes display negative and positive correlations, respectively. ROS reactive oxygen species, sDF sperm DNA fragmentation, NC non-capacitation, AR acrosome reaction, PN pronuclear, Cap capacitation, Motility progressive sperm motility. ^, *, **, and *** indicate P < 0.15, P < 0.05, P < 0.01, and P < 0.001, respectively. The scale bar shows the relationship between the variables.
