Lymphatic filariasis transmission 10 years after stopping mass drug administration in the Gomoa west district of Ghana.
Article in International journal of infectious diseases : IJID : official publication of the International Society for Infectious Diseases, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled it.
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
objectivesA survey was conducted 10 years after stopping MDA in the Gomoa West District of Ghana to assess the Wuchereria bancrofti prevalence in both human and mosquito populations.
methodsIn seven communities, infection in humans was assessed using the filariasis test strip (FTS). Mosquitoes were collected once a month over six months using pyrethrum spray catches (PSC). The mosquitoes were analyzed for W. bancrofti infections, using dissection followed by poolscreening PCR.
resultsFTS results showed that 2/524 (0.38%; 95% CI, 0.0%-0.9%) individuals tested positive for antigen. Dissections revealed W. bancrofti infections in 5/107 Anopheles gambiae (4.7%: 95% CI, 2.2-8.5) from one community, with three mosquitoes harboring L3 larvae (2.8%: 95% CI, 0.9-7.5). PCR analysis of 683 mosquitoes in 57 pools revealed seven positive pools from two communities. The prevalence of infected mosquitoes by PCR for the district was 3.1% (95% CI, 0.5-24.0) for An. gambiae and 2.5% (95% CI, 0.4-23.5) for all Anopheles spp.
conclusionsThe infection rate in the Anopheles spp. exceeds the provisional 1% threshold suggested by WHO, indicating ongoing transmission risk ten years after stopping MDA. Further district-wide assessments are recommended to inform the scope of any interventions required in the Gomoa West district.
