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

The relationship between gut microbiota and host health and disease is intricate, with microbiota-derived metabolites playing a crucial role in the gut-organ axis. In this study, we observe significantly decreased levels of microbial metabolites, particularly tryptophan derivatives in osteoporosis mice. Loss of tryptophan induced intestinal epithelial barrier dysfunction which compromised intestinal barrier integrity, leading to bone inflammatory responses and pathological osteoporosis. Through supplementation of tryptophan-producing bacteria, we effectively repair damaged intestinal barriers in colitis mice and mitigate bone loss, indicating the link between chronic colitis and osteoporosis. This approach offers a promising synthetic biology-based strategy to improve osteoporosis therapy by targeting gut tryptophan. This intervention also alleviates age-related osteoporosis in an aged mouse model, providing a potential therapeutic avenue for combating osteoporosis, a disease of growing concern in aging populations.
