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

purposeBar displacement remains one of the most clinically significant complications of the Nuss procedure for pectus excavatum. To our knowledge, no bibliometric analysis has systematically mapped the research landscape of bar stabilization methods. This study combines bibliometric analysis with clinical systematic review to fill this gap.

methodsA dual-database retrieval from Web of Science Core Collection (WoSCC) and PubMed identified publications on Nuss bar stabilization (1998-2025). Following PRISMA 2020 guidelines, 283 publications were included for bibliometric analysis using VOSviewer, CiteSpace, and R-bibliometrix, and 42 core studies were selected for clinical systematic review. Six fixation categories encompassing 19 techniques were analyzed.

resultsPublications showed exponential growth across four phases. The USA (31.1%) and South Korea (20.0%) led research output. Journal of Pediatric Surgery and Pediatric Surgery International were identified as Zone 1 core journals. Keyword burst detection revealed a shift from "wire fixation" (2003-2012) to "bridge fixation" and "zero displacement" (2015-2025). Displacement rates decreased from 15% (no stabilizer) to 0% in the largest single-center bridge-fixation series.

conclusionAmong the techniques reviewed, bridge fixation is associated with the lowest reported displacement rates across the approximately 6,500 patients in the 42 studies reviewed, achieving 0% in the largest single-center series (Level III evidence, predominantly retrospective data from a single high-volume center; one RCT available). Adequately powered multicenter trials and formal cost-effectiveness analyses are the field's most pressing needs.
