Sensitivity of the estimated population prevalence of syphilis antibody among men and women to model assumptions

Model assumptions		Population prevalence
		Tijuana				Ciudad Juárez
		Male		Female		Male		Female
Transition matrix	Network sizes	Syphilis RPR−	Syphilis RPR+	Syphilis RPR−	Syphilis RPR+	Syphilis RPR−	Syphilis RPR+	Syphilis RPR−	Syphilis RPR+
Unadjusted	Unadjusted	84.79	9.34	2.08	3.8	80.61	3.76	3.76	11.86
Unadjusted	Adjusted	72.37	16.35	0.77	10.5	90.47	1.75	3.16	4.62
Smoothed	Unadjusted	84.81	8.98	2.75	3.45	87.94	3.97	4.69	3.41
Smoothed	Adjusted	73.35	15.94	1.04	9.67	93.28	1.74	3.72	1.25

Smoothed transition matrices are obtained by using the fitted values from the best fitting model in Table 3. Adjusted network sizes are obtained as described in Salganik and Heckathorn.³³
