Fig. 3.

Principal component (PC) scores for male and female participants in the left column (A, C, and E) and menstrual cycle phase in the right column (B, D, and F). Open pink circles represent individual female participants and the open blue squares represent individual male participants. The filled pink circle and blue square represent the mean score for the female and male participants, respectively. The open green diamonds represent individual female participants in the follicular phase and open purple triangles represent individual female participants in the luteal phase and the filled green diamonds and purple triangles represent the group mean respectively. Error bars indicate standard error. Note that in C and D, the filled markers are overlapping and thus are difficult to differentiate.
