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

Background and Objectives: This article focuses on the effects of six heavy metals on gut microbiota, which plays a key role in human health. Gut microbiota plays a key role in metabolism, immunity, and maintaining homeostasis. Heavy metals can affect microbiota composition and function, with health consequences. Consuming large amounts of heavy metals may have harmful impacts, including alteration in microbial composition and bacterial population changes. Materials and Methods: Six heavy metals-cadmium, chromium (toxic metals), copper, zinc, iron, and selenium (beneficial trace elements)-were detected in peripheral blood, serum, or urine, while feces were used for 16S rRNA sequencing. Serum samples from 100 volunteers from Tehran (polluted area) and Firoozkooh (clean city) were collected. Subjects were analyzed for the presence of Results: Conclusion: Some heavy metals change intestinal microbiota composition and metabolic profiles, potentially resulting in metabolic diseases and environmental risks.
