Geographical-ecological coverage of studies on Chagas disease vector control and surveillance.
Study site locations (black dots) are overlaid on the World Wildlife Fund ecoregional map of Latin America (available with detailed ecoregion legends at www.conserveonline.org/docs/2001/06lac_ecoregions.jpg).

Figure 3.
Detection of Chagas disease vectors by notification by residents vs. alternative methods: estimated odds ratios and 95% confidence intervals.
NR, notification of vector presence by residents; AS, active searches by vector control staff (ASfo, using a flushing-out agent); DDgn, vector-detection devices (Gómez-Núñez boxes); (h), results regarding bug presence inside houses; (p), results in the peridomestic area; the reference number and sample size are indicated in parentheses; studies were ranked by mean effect size; the vertical dashed line indicates no effect; effects are significant at the 95% level when the CI does not cross the dashed line; point estimate values >1 indicate a positive effect of the first method in the comparison; see Table 2 for details.

Detection of Chagas disease vectors by vector-detection devices vs. alternative methods: estimated odds ratios and 95% confidence intervals.
AS, active searches by vector control staff (ASfo, using a flushing-out agent; ASkd, using full insecticide application to ‘knock-down’ the bugs); DD, vector-detection devices (DDgn, Gómez-Núñez boxes; DDmb, ‘María’ boxes; DDb, box; DDps, paper sheet; DDp, plastic boxes); (p), results in the peridomestic area; the reference number and sample size are indicated in parentheses; studies were ranked by mean effect size; effects are significant at the 95% level when the CI does not cross the dashed line; point estimate values >1 indicate a positive effect of the first method in the comparison; see Table 3 for details.
