CD14 and pelvic inflammatory disease: To support this determination of biomarker specificity, we also searched Pubmed for publications related to the 14 cytokines and disorders that incur gynecological inflammation, including “endometriosis,” “pelvic inflammatory disease,” “polycystic ovarian syndrome,” “pelvic adhesion,” “sexually transmitted disease,” “uterine fibroid,” “uterine cancer,” and “ovarian cancer.” Two of the proteins, CD14 and TNF-β, have been previously associated with all the conditions in at least 2 publications and an overall average of ~ 90 publications (Additional file 3: Table S6).
