Among the controls, those with dyspareunia had lower levels of IL-8 (GMpresent = 4.64 [95% CI = 4.41–4.89] pg/mL vs. GMabsent = 4.99 [95% CI = 4.82–5.17] pg/mL; p = 0.02), and the IL-8 levels were lower for controls reporting pain with bowel movements (GMpresent = 4.66 [95% CI = 4.43–4.89] vs. GMabsent = 4.96 [95% CI = 4.82–5.11] pg/mL, p = 0.03). Here, CXCL8 is linked to Dyspareunia.
