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
backgroundExtracorporeal Membrane Oxygenation (ECMO) is a critical life-support technology widely used for managing patients with cardiopulmonary failure. However, ECMO patients are particularly susceptible to healthcare-associated infections (HAIs) due to their critical illness and the invasive procedures. These infections not only reduce patients' quality of life but also increase healthcare resource utilization. Therefore, understanding the characteristics and risk factors of HAIs in ECMO patients and establishing/implementing targeted preventive strategies are essential.
objectiveThis study aimed to analyze the epidemiological characteristics of HAIs, investigate associated risk factors, and assess the economic impact on patients receiving ECMO support.
methodsThis cohort study included patients who received ECMO support at Taihe Hospital, Hubei University of Medicine, from February 2017 to September 2023. Patients were categorized into an infection group and a non-infection group based on the occurrence of HAIs. Collected data included basic patient information, infection sites, pathogen distribution, and economic burden. Risk factors for ECMO-related HAIs were analyzed using both univariate and multivariate methods, with statistical significance defined as p < 0.05. Multivariate competing risk regression analysis was performed to identify independent risk factors significantly associated with ECMO-related HAIs.
resultsThe study included 97 eligible ECMO patients, predominantly male (77, 79.38%), with a mean age of 46.7 ± 16.5 years. The total ECMO support duration across all patients was 467.3 days, with a median hospital stay of 12.5 days (range: 4.4-25.5 days). Of note, 86.60% of the patients received venoarterial (VA) ECMO support. Among these patients, 14.43% developed ECMO-related HAIs, resulting in 17 HAI events among 14 patients. These events comprised 10 respiratory tract infections (RTIs), 4 bloodstream infections (BSIs), 2 surgical site infections (SSIs), and 1 urinary tract infection (UTI). The rate of ECMO-related HAIs was 36.4 cases per 1,000 ECMO days. A total of 29 pathogenic microbial strains were identified, including 21 multidrug-resistant bacteria (72.41%; 72.41% Gram-negative, 20.69% Gram-positive), and 2 fungal strains (6.90%). Independent risk factors for ECMO-related HAIs included tracheostomy (odds ratio [OR] = 28.6, p = 0.003) and decreased platelet count (OR = 0.975, p = 0.004). Median total hospitalization expenses were significantly higher in the infection group (US$100,270.4 vs. US$32,108.6; p < 0.05).
conclusionsPatients receiving ECMO support are at a heightened risk of developing HAIs, with respiratory tract infections (RTIs) and bloodstream infections (BSIs) being the most prevalent types. The study identified tracheostomy and decreased platelet count as independent risk factors for ECMO-related HAIs. These infections result in prolonged hospital stays and increased economic burden. Therefore, targeted preventive strategies that address these risk factors should be prioritized to reduce infection incidence, aiming to reduce the incidence of infections and alleviate the associated financial burden.
