Abbreviations: CI, confidence interval; MTZ, metronidazole; RR, risk ratio; TOC, test of cure; TV, Trichomonas vaginalis; TVV, Trichomonas vaginalis virus; TVV+, TVV-positive; TVV−, TVV-negative.

^aOf 355 women, 322 returned for a TOC follow-up visit (after drug treatment).

^bAt TOC by nucleic acid amplification test, 47 women remained persistently positive for TV.

^cOnly 25/47 isolates were tested for MTZ resistance, due to difficulty growing in vitro.
