Submicroscopic infections and two malaria vectors are major contributors to residual malaria in an Amazonian village in Peru.
Article in Scientific reports, 2025. 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
In the Loreto region of Amazonian Peru, the primary malaria vector is Nyssorhynchus (or Anopheles) darlingi. The present year-long study sought to identify specific landscapes with the greatest risk of Plasmodium transmission, incorporating epidemiological data, landscape stratification models, satellite imagery, and vector biology. A monthly longitudinal cohort study and population screening of all residents of the focal village Santa Rita detected, among 353 inhabitants enrolled, a ratio of 17:1 submicroscopic/ microscopic malaria infections. Microscopy-detected human infections were seasonal, generally peaking with rising river levels and increasing rainfall, but submicroscopic infections, detected by qPCR, were perennial. Despite high mosquito net usage, inhabitants with outdoor occupations had significantly higher P. vivax infection rates compared with those with indoor occupations or those not working (35% vs. 21%, p = 0.012). A spatial grid subdivided the study area into anopheline mosquito sampling units where mosquitoes were collected monthly. Plasmodium-infected specimens of Ny. darlingi were detected in each of the 5 landscapes that were determined by a cluster analysis. A putative secondary vector, Anopheles near costai G1, was infected with Plasmodium vivax and Plasmodium malariae, reported herein for the first time in Peru. Overall, the most pathogenic landscape was degraded forest.
