Table 6.

The impact of return treatment on time required for gonorrhoea and chlamydia to be eliminated and on chlamydia prevalence

Return treatment probability (%)	Number of eliminations (out of 100 runs)	Years required for elimination of gonorrhoea
		Median	25th-75th percentile
0	94	25.0	17.0-36.9
5	100	10.3	7.8-13.0
10	100	10.3	7.9-14.0
Return treatment probability (%)	Number of eliminations (out of 100 runs)	Chlamydia prevalence at the end of 60 years (%)
		Median	25th-75th percentile
0	0	7.0	6.0-8.7
5	2	3.5	2.1-4.6
10	27	1.0	0-2.2

For all simulation runs in the figure, residents with symptoms will be treated at a rate such that 25% of infected individuals receive treatment in 25 days (i.e. at a rate of 0.011 per day). Under return treatment, all symptomatic and a proportion (5% and 10%) of asymptomatic infected non-residents are treated upon return to their home location.
