Microplanning for entomological surveys to sustain the onchocerciasis elimination effort in West Africa.
Article in International health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundFormer Onchocerciasis Control Programme countries like Senegal have made important progress towards eliminating onchocerciasis. Senegal has engaged in post-mass drug administration (MDA) activities, mainly entomological surveillance, but the country initially struggled to collect the recommended number of blackflies in all the country's transmission zones. Here, we implemented a simple approach in the entomological surveillance protocol to increase the number of Simulium damnosum collected.
methodsThe study was conducted over two consecutive years, 2022 and 2023, in the main S. damnosum capture points located along the Gambie and Falémé river basins. We reviewed environmental data, analysed and interpreted previous blackflies capture data and processed field visits to identify optimal periods of blackfly capture in each capture point.
resultsAfter the implementation of our approach, the number of blackflies captured increased by approximately 42% in 2023 compared with 2022 captures. The numbers of blackflies captured increased from 71 999 and 23 666, respectively, in Gambia and Falémé in 2022, to 101 276 and 34 780 in 2023.
conclusionOur results reveal that simple and effective microplanning of blackfly capture periods can support onchocerciasis post-MDA surveillance activities by increasing the number of blackflies captured.
