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

Traumatic brain injury (TBI) induces both neuroinflammation and gut microbiome dysbiosis, yet the influence of antibiotics (ABX) on TBI-related neuropathology remains unclear. We administered a broad-spectrum oral ABX regimen to deplete the gut microbiome in single and repeated TBI mouse models. In male mice, ABX treatment significantly reduced neuroinflammation and neurodegeneration post-TBI, with no effects observed in uninjured controls. ABX also altered microbiome composition and decreased serum and fecal short-chain fatty acid levels, while intestinal damage and dysbiosis were further exacerbated by TBI severity. Notably, germ-free male mice exhibited heightened neuroinflammation and larger lesion volumes following TBI, underscoring the microbiome's essential role in recovery. Metagenomic analyses revealed
