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.
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
objectivesThis study presents the 5-year experience with a more liberal intraoperative extracorporeal membrane oxygenation (ECMO) elective support in patients with pulmonary fibrosis (PF) undergoing lung transplantation (LTx).
methodsPatients with PF undergoing LTx between January 2012 and January 2025 were included and sub-divided into the period before and after the implementation of a more liberal intraoperative use of ECMO support in January 2020. Outcomes were compared between elective, non-elective, and no intraoperative ECMO in both periods. Previously-identified parameters as decision criteria for elective ECMO were examined.
resultsOverall, 422 PF patients underwent LTx, of whom 273 patients were transplanted before 2020 (elective ECMO, n = 52 (19%); non-elective ECMO, n = 30 (11%); no ECMO, n = 191 (70%)) and 149 patients were transplanted since 2020 (elective intraoperative ECMO, n = 98 (66%); non-elective ECMO, n = 12 (8%); no ECMO, n = 39 (26%)). After 2020, elective ECMO was increasingly used in patients with mean pulmonary arterial pressure >50 mmHg and pulmonary vascular resistance >9.4 WU. However, 8% were not identified based on these parameters and still required non-elective ECMO. Comparing pre- and post-2020, primary graft dysfunction (PGD) grade 3 72 h post-transplant between elective (17% vs 3%, P = .002), non-elective (38% vs 0%, P = .016), and no ECMO (12% vs 3%, P = .078) was significant reduced. One-year graft survival in elective (88.5% vs 95.6%), non-elective (70% vs 91.7%), and no ECMO (92.7% vs 94.9%) showed a trend towards improved survival.
conclusionsThe use of a more liberal, elective intraoperative ECMO support in patients with PF led to an improvement of PGD prevalence and survival early after lung transplantation.
