	No. of sex partners	No. of serodiscordant/status unknown partners	Odds of (any) serodiscordant/status unknown partners	Odds of (any) sex without a condom and multiple partners

Unadjusted model
Time (ref = baseline)
Follow-up 1	0.72 (0.62, 0.84)^***	0.62 (0.47, 0.82)^***	0.67 (0.48, 0.94)^*	0.41 (0.26, 0.64)^***

Follow-up 1	Model reduced to unadjusted model (above)	Model reduced to unadjusted model (above)	Model reduced to unadjusted model (above)	0.40 (0.25, 0.65)^***

Covariates for age and CBO were removed from multivariable models for all outcomes based upon selection of the best fitting model.
