^aAdjusted for secular trends plus drug use, recent incarceration and homelessness; fixed covariates (age, sex, race, etc.), which represent between- rather than within-subject differences, have no influence in the conditional logistic model.

^bOR for behavior immediately after seroconversion; model assumes change at seroconversion followed by linear trend
