1 · What the graph read from it

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.

2 · The registry

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

objectiveTo characterize aflatoxin B1 (AFB1) contamination, oil-quality variation, workshop hygiene, and modeled dietary risk associated with artisanal peanut oil produced by small-scale workshops in Nanning, China.

methodsA cross-sectional study was conducted in 144 workshops across all 12 county-level administrative areas of Nanning, with one peanut-oil sample collected from each workshop. On-site hygiene practices were assessed using a structured 13-item instrument. AFB1 concentration, acid value, and peroxide value were measured using national standard methods. Regional differences were evaluated using non-parametric tests, and K-means clustering was applied to characterize multivariate quality profiles. Dietary exposure was assessed using estimated daily intake (EDI), margin of exposure (MOE), and modeled AFB1-attributable hepatocellular carcinoma (HCC) risk.

resultsAFB1 was detected in 88.2% of samples, while 3.5% exceeded the Chinese maximum level of 20 μg/kg. Samples from counties had significantly higher AFB1 concentrations, acid values, and peroxide values than those from municipal districts (all

conclusionsArtisanal peanut oil from small-scale workshops in Nanning showed frequent AFB1 detection, marked regional variation in multiple quality indicators, and limited implementation of contaminant-specific control practices. These findings support closer attention to routine AFB1 monitoring, storage management, and broader quality control, particularly in county settings.
