Metal levels in bat guano from Brazilian caves: insights into environmental contamination.
Article in Environmental monitoring and assessment, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Bats, with more than 1450 species worldwide, roost in caves, and colonies can produce guano deposits. Guano analysis reveals bat diets and indicates environmental contamination, since bats interact and accumulate metals through food, water, and airborne particulate matter. This study examined guano from caves in Rio Grande do Norte (RN-27 samples) and Pará (PA-24 samples), Brazil, to assess metal levels. Samples were taken from different depths, locations, and species, including the omnivorous Phyllostomus discolor, insectivorous Pteronotus gymnonotus, and nectarivorous Glossophaga soricina. Microwave-assisted acid digestion was used, and a 2
