[Seasonal transmission of malaria in the Senegal River Valley: case study of the city of Kaedi-Mauritanie].
Article in The Pan African medical journal, 2019. 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
introductionIn the face of environmental and climatic changes both ongoing and planned, the epidemiology of malaria in the city of Kaedi (Mauritania), along the Senegal River Valley, requires special attention. Some cases of malaria have been registered in the health facilities throughout the year, with an average of 150,000 annual suspected cases and climatic and ecological conditions which are now favorable for seasonal transmission.
methodsWe conducted two cross-sectional descriptive surveys in the city of Kaedi in September 2014 (wet season) and in May 2015 (dry season). Our cluster sampling involved 700 households. Microscopic examination was performed in all household members. Furthermore, larval surveys, early morning wildlife spraying and nocturnal traps breaking were performed.
resultsDuring both seasons, 9.313 thick smears were manufactured, 15 were positive, with a plasmodium prevalence rate of 0.16%. Among these, 12 were positive in the dry season and 3 in the rainy season. Plasmodium prevalence rate was 0.26% and 0.06% respectively in the dry season (n = 4642) and in the wet season (n = 4671). In the rainy season, rates were 0.04% (2/4671) and 0.02% (1/4671) respectively for Plasmodium malariae and Plasmodium falciparum. The only species found in the dry season was Plasmodium falciparum. Entomological investigations showed the presence of a single species of Anopheles mosquito, Anopheles gambia (two in the rainy season and six in the dry season). Larval surveys showed that the larval fauna was dominated by Culex larvae (99.6%). Anopheles larvae (0.4%) were collected only during the dry season.
conclusionDespite low malaria transmission in the city of Kaedi, in a context of lack of rainfall, health authorities should implement a strategy for malaria elimination in the wilayas of the Senegal River.
