Aflatoxins and fumonisins in nixtamalized corn dough from El Salvador: A two-year survey.
Article in Toxicology reports, 2025. 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
Corn is a staple of the Salvadoran diet but is vulnerable to contamination by aflatoxins and fumonisins. While these mycotoxins have been studied in nearby countries, El Salvador lacks similar data, despite over 90 % of its population consuming corn derivatives. This study aimed to monitor aflatoxin and fumonisin levels in nixtamalized corn dough used for making tortillas and assess daily intake for potential exposure. Aflatoxin-positive cases were low at 20 %, with less than 2 % of samples exceeding 10 µg/kg, and none exceeded this limit on average. Fumonisin-positive cases were also low (< 7 %) and only detected in the dry season, with all cases exceeding the maximum limit of 1 mg/kg. The estimated daily intake of aflatoxin exceeded the recommended guidance value of 0 ng/kg body weight per day, varying by locality and season. Moreover, all fumonisin daily intake measurements surpassed the maximum limit of 1 µg/kg body weight per day, showing no seasonal variation. Thus, consuming nixtamalized corn dough contaminated with these mycotoxins poses a potential health risk to Salvadorans.
