Table 4

HIV/STI testing and sexual behaviors self-reported by men who had syphilis testing during the trial and initiated at least 1 follow-up survey.

MD = mean difference. RD = risk (probability) difference expressed as a percentage.

aDue to rounding error, mean differences may differ by one decimal place from differences obtained by subtracting means listed in table.

bOther STIs included gonorrhea, chlamydia, human papillomavirus, and herpes simplex virus.

CI, confidence interval; SOC, standard of care; SST, syphilis self-testing; STI, sexually transmitted infection.
