Comparison of two adult mosquito sampling methods with human landing catches in south-central Ethiopia

Malaria Journal

Table 3 Mean log ratios and corresponding geometric mean ratios of alternative mosquito collection methods (light traps, LTC and CO₂-baited light traps, CB-LTC) against the reference method (human landing catches, HLC) for sampling Anopheles species in Edo Kontola, Ethiopia

Species	Alternative method vs. HLC	Venue	Mean log ratio^a	Standard error of the mean (S. E. M.)	Geometric mean ratio (GMR)	95% CI

^aNegative mean log ratio indicates that the efficiency of LTC or CB_LTC were lower than HLC
