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
In the Sahel, malaria transmission is highly dependent on rainfall, and control efforts are conducted during the rainy season. However, because of climate changes, the objectives of this study were to better define the period of transmission in the different ecoclimatic regions and the burden of the disease in young adults, which is poorly investigated. The data from districts in the different ecological zones of Niger were compared. During this study, 26% of all consultations were malaria related, of which 59% were malaria confirmed. This represented 12,000 to 19,000 cases and 12.9 to 25.6 deaths per 100,000 inhabitants. An increase of incidence was seen over the study period but a decline in case fatality rate was also observed. Depending on region, children under 14 years of age (half of the population) accounted for 43-80% of cases, which in contrast, underlines a significant malaria burden in young adults, especially in arid regions where transmission is lower. The majority of cases occurred from August to October but appeared later in arid zones. The number of cases positively correlated with the cumulative rainfall over the previous five weeks. However, 17-26% of cases were identified during the dry season. This study highlights a high transmission rate that extends throughout the dry season, with ∼50% of cases registered representing patients >14 years of age, and 25% of cases >25 years. Young adults should thus be considered an at-risk group and should be included in strategies for control.
