Urban malaria in Accra, Ghana: transmission risk and influence of irrigated vegetable farms.
Article in BMC infectious diseases, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Urban malaria transmission in sub-Saharan Africa is often underestimated, emphasizing the need for research on vector distribution, abundance, behavior, and infectivity in cities. Urban malaria transmission has been on the rise across sub-Saharan Africa since 2003. Also, monitoring Anopheles populations is crucial for developing effective interventions. This study examined the biting and resting habits, distribution, abundance, and Plasmodium infection of malaria vectors in Accra. Adult malaria vectors were collected using human landing catch (HLC) and Prokopack aspiration (PPK) at ten sites in Accra, categorized into five groups: sites with Irrigated Urban Farming (IUF), Lower Socioeconomic Status (LS), Middle Socioeconomic Status (MS), High Socioeconomic Status (HS), and Peri-urban (PU) areas. Biting patterns and entomological transmission indices of malaria vectors were assessed. Molecular methods were used to detect sporozoite infection, bloodmeal sources, vector species, and insecticide resistant mutation genes. A total of 41,747 mosquitoes were collected. Of these, 95.49% (39,863/41,747) were host-seeking collected through human landing catch (HLC), consisting of Anopheles (52.54%, 20,945/39,863), Culex (42.00%, 16,742/39,863), Aedes (3.74%, 1,491/39,863), and Mansonia (1.72%, 685/39,863). The remaining 4.51% (1,884/41,747) were resting mosquitoes collected using a Procopack aspirator, comprising Anopheles (31.26%, 589/1,884), Culex (57.21%, 1,078/1,884), and Aedes (11.52%, 217/1,884). Overall, the IUF site category had the highest abundance of An. gambiae s.l. (48.63%, 10,466/21,520), followed by the PU (18.06%, 3,887/21,520), HS (16.42%, 3,533/21,520), MS (13.74%, 2,956/21,520) and LS (3.15%, 678/21,520) in both HLC and Procopack collections. Indoor An. gambiae s.l. had higher sporozoite infectivity (4.56%, 16/351) than outdoor (3.78%, 9/238) (χ
