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

Host-microbiota interactions during the neonatal window of opportunity have gained significant interest as factors influencing long-term health. Factors such as nutrient availability may shape the microbial community, and iron is no exception to this rule. Although the use of iron supplementation is widespread during infancy, this micronutrient is known to have profound effects on gut microbiota. This study aimed to determine how early-life iron supplementation shapes gut microbiota composition and whether it influences recovery from gut dysbiosis later in life. Three-week-old female C57BL/6 mice were fed an iron-excess diet for five weeks during the critical period of microbiota establishment. After a two-week washout period to normalize luminal iron content, dysbiosis was induced using either dextran sulfate sodium-induced acute colitis or antibiotic treatment. Mice were then allowed an 8-week recovery period. Gut microbiota composition was longitudinally analyzed by 16S rRNA gene sequencing of fecal samples. Early-life iron supplementation induced durable alterations in gut microbiota composition, with differences persisting even after luminal iron normalization (β-diversity, PERMANOVA
