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

Aging and inflammation of the intestinal and oviductal mucosa reduce egg production in laying hens. In mammals, microbiota changes in the intestine and reproductive mucosa are linked to aging and mucosal inflammation, but this relationship remains unclear in hens. The present study aimed to investigate the impact of aging on microbiota and inflammation in the intestinal and oviductal mucosa of hens. Sixteen White Leghorn hens aged ~280 days (young) and ~730 days (aged) were used. Bacterial DNA was extracted from feces and vaginal swabs for 16S rRNA amplicon sequencing. Intestinal (ileum and cecum) and oviductal (uterus and vagina) tissues were processed for histological analysis. Real-time PCR was performed to profile pro- and anti-inflammatory cytokines, tight junction-related molecules, and calbindin in the uterus. Whereas microbial diversity and composition in the vagina did not change with age; alpha-diversity of intestinal bacteria was lower in the aged group, as suggested by 46 genera showing a decrease and five an increase. The morphology of the ileum mucosa deteriorated, with transforming growth factor (
