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

Legg-Calvé-Perthes disease (LCPD) is a rare pediatric disorder characterized by avascular osteonecrosis of the femoral head. Its pathogenesis is multifactorial, and genetic, epigenetic, vascular, and inflammatory mechanisms may contribute to disease susceptibility and progression. To map and characterize the available evidence on genetic and epigenetic factors and molecular pathways associated with LCPD, with particular emphasis on potential interactions and convergence across biological pathways. A scoping review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR, PRISMA 2020 for Abstracts checklist). PubMed/MEDLINE was searched for studies published between March 2006 and March 2026. Relevant genetic, epigenetic, and molecular findings were extracted and synthesized according to biological pathways. See the PRISMA 2020 for Abstracts checklist. Seventeen genes and 25 single-nucleotide variants (SNVs), as reported in the included literature, were identified and grouped into three major biological axes: hypercoagulability, inflammation, and bone metabolism and remodeling. Associations with LCPD were reported in at least one study for
