The prevalence of gonorrhoea (top) and chlamydia (bottom) at 60 years after introduction of STI, with periodic variations in non-resident proportion. The percentages on the horizontal axis are the percentage adjustment to the non-resident proportion for the first half and second half of the each year. For example, simulations runs in box labelled (150%, 50%), will have non-resident proportion at 1.5 times of the values listed in Table 4 during the first half of each year, and 0.5 times of the values listed during the second half of each year. See the caption of Figure 3 for the description of the box plot.
