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: Ex vivo lung perfusion (EVLP) has expanded the use of donor lungs by enabling ex vivo assessment, preservation, and rehabilitation before transplantation. Despite these advances, ischemia-reperfusion injury, inflammatory activation, pulmonary edema, and impaired lung mechanics continue to compromise graft quality and contribute to primary graft dysfunction. Inhaled and gaseous interventions have emerged as potential adjunctive therapies to improve donor lung preservation during EVLP; however, a standardized protocol has not yet been established. Methods: PubMed and Embase were used to search human and animal studies evaluating inhaled and gaseous interventions administered during and after EVLP. Articles published from the database's inception to September 22, 2025, were analyzed. Results: Among the interventions examined, 10% carbon dioxide, carbon monoxide (CO), 40% oxygen (O Conclusions: Inhaled interventions can attenuate both mechanical damage and inflammatory pathways, particularly when used in tailored combinations with 40%-60% O
