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

Background: Axial spondyloarthritis (axSpA) is a chronic inflammatory disease affecting the spine and sacroiliac joints. Emerging evidence suggests that the gut microbiota may contribute to its pathogenesis, but findings on microbial diversity and composition remain inconsistent. Methods: We systematically searched PubMed, Embase, Web of Science, and the Cochrane Library to identify studies comparing the gut microbiota between adults with axSpA and healthy controls. α-Diversity (Observed richness, Shannon, Simpson, Chao1, ACE) and microbial composition at the phylum level were extracted. Random-effects meta-analyses were performed using standardized mean differences (SMDs), with subgroup analyses and robustness checks (prespecified sensitivity and leave-one-out analyses). Results: Twenty-five studies (n = 1639) were included. Compared with controls, axSpA was associated with lower α-diversity for Observed richness (SMD = -0.59, Conclusion: axSpA is associated with reduced α-diversity and compositional shifts in gut microbiota, but the magnitude of effects varies across studies. Heterogeneity and methodological differences warrant cautious interpretation. Longitudinal and functional studies are needed to clarify causality and therapeutic implications.
