The Host, agent, and environment factors correlations (a) and differences between the sexes (female-male) (b). In (a), a positive association is coded in red, and a negative association is coded in blue. In the heatmap reporting sex differences (b), the red color indicates that if the correlation in a sex-specific heatmap was positive (i.e., red color), females have a stronger positive correlation between those two variables than males, and if it was negative (blue color), females have a weaker correlation than males. The blue color in (b) indicates that if the original correlation was positive, males have a stronger positive correlation between those two factors, and if negative, males have a weaker correlation than females
