Data are among men in the primary evaluable population who have analyzable Day 15 data, are positive for Mycoplasma genitalium only, and were treated with azithromycin, stratified by the presence or absence of macrolide resistance mutations (23S rRNA), July 2017–June 2018.

Abbreviations: CI, confidence interval; rRNA, ribosomal ribonucleic acid.

aAmong 97 (74 with 23S mutations present and 23 without) participants with analyzable Day 15 data.

bAmong 113 (85 with 23S mutations present and 28 without) participants with analyzable return data.
