Table 3.

The sensitivity to the relative increase in the number of morbidity case years averted by annual community-wide treatment to the level of coverage in adults

		Community-wide treatment
Transmission setting	Intensity thresholds for morbidity	Adult coverage: 75 %	Adult coverage: 55 %	Adult coverage: 35 %
Intermediate	Lower	749 %	520 %	339 %
	Higher	317 %	258 %	203 %
High	Lower	394 %	275 %	168 %
	Higher	527 %	439 %	327 %

Percentage gain is relative to annual child-targeted treatment with a coverage of 75 %. The effect is expressed in terms of morbidity case years prevented i.e. the number of years lived with morbidity averted across the time horizon. For each year the effectiveness was calculated as the difference between the number of cases and the number in absence of treatment. Assumptions are as in Table 2
