^*A total of 135 women had evaluable endometrial histological data.

^†Model for M. genitalium positive women was adjusted for race, chlamydia, gonorrhoea and bacterial vaginosis. The models for M. genitalium monoinfection or coinfection were adjusted for race and bacterial vaginosis.

^‡M. genitalium negative includes all women who tested negative for M. genitalium at the cervix or endometrium. M. genitalium positive includes all women who tested positive for M. genitalium at the cervix or endometrium.

^§M. genitalium mono (no coinfection with chlamydia or gonorrhoea) or coinfection with chlamydia or gonorrhoea.
