Repression of microbial arsenite uptake and methylation by dissolved organic carbon.
Article in Environmental science & technology letters, 2024. 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
Arsenic methylation is the microbe-mediated transformation of inorganic As into methylated species, an important component of the biogeochemical arsenic cycle in rice paddies. Prior to methylation, arsenite is taken up into bacterial cells through GlpF, an aquaglyceroporin channel for uptake of glycerol and other low-molecular-weight organics. The uptake and subsequent biotransformation of arsenite are therefore linked to the bacterial utilization of organics. We hypothesized that increasing concentrations of carbon substrates will repress the uptake and methylation of arsenite through a carbon catabolite repression (CCR) mechanism. An arsenic biosensor assay demonstrated that arsenite uptake was repressed in the presence of glucose and environmental dissolved organic matter (DOM) isolates. RT-qPCR analysis of
