Example of how to read the table: The odds of an MSM diagnosed with HIV who met his last non-steady anal sex partner online having received a bSTI diagnosis in the recent 12 months are 4.93 compared with those of an MSM not diagnosed with HIV. The odds of a man not diagnosed with HIV who met his non-steady anal sex partner in a gay sex venue were 1.88 compared with those of a man meeting his last non-steady anal sex partner online. The odds of a man diagnosed with HIV who met his last non-steady anal sex partner in a gay sex venue were 1.52 compared with those of a man diagnosed with HIV and meeting his last partner online, and 1.52*4.93=7.49 compared with those of a man not diagnosed with HIV meeting his last partner online.
bSTI, bacterial sexually transmitted infections; MSM, men having sex with men.
