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

Osteoporosis (OP), a major global skeletal disorder characterized by reduced bone mass and increased fracture risk, is increasingly understood through the lens of the gut‑bone axis. The present review critically synthesizes mechanistic and translational evidence for two classes of gut microbial metabolites short‑chain fatty acids (SCFAs) and polyamines, as active regulators of bone remodeling. SCFAs (acetate, propionate and butyrate) suppress osteoclastogenesis via the TRAF6/NFATc1 pathway, promote osteoblast differentiation through GPR43/GPR109A signaling and histone deacetylase inhibition, and expand immuno‑protective regulatory T cells in the bone marrow. Microbial polyamines (spermidine, spermine and putrescine) promote osteogenesis by upregulating Runx2 and alkaline phosphatase and inhibit osteoclastogenesis through suppression of the Ca²
