Comparison of Oviposition and Adult Trapping to Monitor wMel Introgression for Wolbachia-Based Vector Control.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Wolbachia introgression into Aedes aegypti (Ae. aegypti) mosquito populations is an effective strategy for preventing dengue and is currently under evaluation for WHO prequalification. The standard protocol for trials and deployments currently being conducted in Brazil by the World Mosquito Program (WMP) for long-term monitoring of Wolbachia introgression involves the use of BG-Sentinel traps (BG-traps; Biogents AG [Regensburg, Germany]), which are labor-intensive and costly. More affordable alternatives, such as oviposition traps (ovitraps), have been used in other settings; however, a comparison of the WMP protocol for Wolbachia surveillance has not been performed. As part of the EVITA dengue trial, Ae. aegypti eggs and adults were collected from 124 ovitraps and 237 BG-traps across 12 clusters in Belo Horizonte, Brazil, between March and May 2023. Eggs collected from ovitraps were reared to L3 and L4 larvae, and wMel Wolbachia was detected using quantitative polymerase chain reaction testing in larvae and adult mosquitoes from BG-traps. Mixed-effects models were used to compare cluster-level estimates of wMel introgression derived from ovitrap and BG-trap data over time. Among 3,675 larvae reared from ovitraps, wMel prevalence was 0.50 (95% CI: 0.48-0.51), whereas 1,244 adults from BG-traps had a prevalence of 0.45 (95% CI: 0.42-0.48). Cluster-level introgression estimates from larvae and adults were strongly correlated (Spearman's r = 0.70; P <0.001). Multivariate models incorporating current- and previous-month ovitrap data and mosquito abundance revealed strong agreement between ovitrap-based predictions and BG-trap estimates (rs ≥0.98). These findings reveal that ovitrap-based surveillance provides a low-resource, efficient, and precise alternative for monitoring Wolbachia introgression as interventions are scaled in high-burden dengue settings.
