The impact of suboptimal participation in routine chlamydia screening. The percentage change in HIV incidence (blue) and chlamydia incidence (red), ten years after the introduction of routine chlamydia screening among HIV-infected MSM in care with suboptimal participation in the screening program: participation is 80% in only one of the four sexual risk groups and 100% in the other three risk groups. The four risk groups are: low risk, fairly high risk, very high risk, and extremely high risk, with increasing number of sexual partners. The results for the case with 100% participation of all HIV-infected MSM in care (first columns in both plots) are shown for comparison. The height of the columns shows the median and the line segments show the interquartile range of the results with the selected parameter sets.
