Point estimates and 95% confidence intervals of the RDS simulations samples for selected infections and risk behaviours (past 30 days)

3a: Distributive syringe sharing

3b: Receptive syringe sharing

3c: Sharing cookers and filters

3d: Using condoms every time during sex

3e: Having two or more sex partners

3f: Prevalence of HAV

3g: Prevalence of anti-HBc

3h: Prevalence of HBsAg

3i: Prevalence of HCV

3j: Prevalence of HIV

3k: Prevalence of Chlamydia

3l: Prevalence of syphilis

Notes:

1. For better visualization and interpretation, point estimates of the simulation samples were ordered by magnitude (the X axis of each chart represents the rank order of the simulation sample point estimates), and only the related confidence interval ranges are depicted (therefore the Y axis ranges are different for each chart both in terms of minimum and maximum values and in terms of units within the ranges between minimum and maximum).
2. Prevalence and, respectively, 95% confidence intervals for each characteristic in the original sample are represented as black and, respectively, gray vertical lines within each chart to provide a visual reference for the point estimates of the simulation samples.
3. Statistically significant difference is when a point estimate of the simulation sample lies either under the lower confidence interval or above the upper confidence interval of the prevalence within the original sample for the relevant characteristic.
