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

Lung transplantation (LTx) remains the definitive treatment for select end-stage pulmonary diseases, yet early graft failure due to acute rejection continues to compromise long-term outcomes. Tissue injury and insufficient reparative responses in the immediate post-transplant period contribute to this vulnerability. Tumor Necrosis Factor-Stimulated Gene-6 (TSG-6) is a multifunctional anti-inflammatory and tissue-protective protein known to facilitate resolution of inflammation and extracellular matrix remodeling, but its role in human LTx remains undefined. In this retrospective study, we examined TSG-6 expression in transbronchial biopsies from two matched cohorts of LTx recipients-those with histopathologically confirmed acute rejection (n = 6) and those without rejection (n = 6)-within the first postoperative month. Immunofluorescence analysis revealed significantly elevated TSG-6 expression in non-rejected grafts across two metrics: whole-biopsy staining intensity (Mean 11 ± 1.6 units vs 2.35 ± 0.5, p < 0.01) and percentage of TSG-6-positive cells (~90% vs. ~30%, p < 0.01). Scatter plot visualization confirmed a clear separation between groups, suggesting that elevated TSG-6 expression-both in total tissue and per-cell prevalence-is strongly associated with the absence of acute rejection and may reflect a reparative immune phenotype. Despite the limited sample size, the consistency and magnitude of the effect (Cohen's d ≈ 4.7) underscore the biological relevance of TSG-6 in early graft stability. Our data establish a novel link between increased TSG-6 expression and diminished acute rejection in human lung allografts, suggesting that TSG-6 may actively modulate alloimmune responses and serve as both a marker of graft stability and a candidate for therapeutic intervention.
