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

backgroundECMO outcomes in COVID-19-related respiratory failure among solid organ transplant (SOT) and hematopoietic stem-cell transplant recipients (HSCT) are poorly described. We investigated: (1) whether transplant patients (SOT/HSCT) with COVID-19 have worse outcomes than non-immunocompromised (IC) COVID-19 patients, and (2) whether among transplant recipients (SOT/HSCT), those with COVID-19 have worse outcomes than those with non-COVID-19-related respiratory failure. Additionally, we aimed to identify factors independently associated with mortality among COVID-19 transplants.

methodsRetrospective analyses of the Extracorporeal Life Support Organization Registry from 1/1/2017 to 31/07/2023. Two comparisons were made: (1) transplant COVID-19 versus non-IC COVID-19, and (2) transplant COVID-19 versus transplant non-COVID-19 patients. Outcomes were analyzed using propensity score (PS)-adjusted, multivariable, and PS-matched analyses, adjusting for a priori identified confounders. Primary outcome was in-hospital mortality.

resultsAmong 38,270 runs, 146 transplant COVID-19, 12,552 non-IC-COVID-19 and 886 transplant non-COVID-19 runs were identified. In-hospital mortality in transplant COVID-19 patients was 75.3% and the risk was invariably increased compared to non-IC-COVID-19 (PS-adjusted OR: 2.36 [95%CI:1.61-3.46], p < 0.001, multivariable OR:2.35 [95%CI:1.59-3.49], p < 0.001, and PS-matched analysis OR: 1.89 [95%CI:1.21-2.95], p < 0.005) and transplant non-COVID-19 patients (PS-adjusted OR: 4.20 [95%CI:2.74-6.44], p < 0.001, multivariable OR: 3.79 [95%CI:2.51-5.74], p < 0.001, and PS-matched analyses OR: 3.17 [95%CI:1.90-5.28], p < 0.001). Mortality difference remained stable over time. Older age independently associated with higher mortality. This was accompanied by higher need for renal replacement therapy compared to non-IC-COVID-19 patients. Compared to transplant non-COVID-19 patients, ECMO runs and time-to-live discharge were invariably prolonged. Hemorrhagic, metabolic, pulmonary and infectious complications consistently occurred more frequently.

conclusionsMortality was high in COVID-19 transplant ECMO patients, warranting cautious use of ECMO in this population.
