Women with high PmpI reactivity were slightly more likely to have elevated CRP (55.6% versus 42.9%), bilateral adnexal tenderness (85.0% versus 75.0%), mucopurulent cervicitis (72.2% versus 58.8%), endometritis (71.4% versus 61.1%), and UGTI (58.8% versus 42.1%) compared to women with low PmpI reactivity although this did not reach statistical significance. The gene discussed is CRP; the disease is endometritis.
