Prevalence and impact of ECMO cannula colonization: a single center study.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
During ECMO therapy, infections are common and have substantial impact on treatment outcomes. However, data on the prevalence and clinical impact of microbial ECMO cannula colonization are scarce. Between October 2020 and May 2022, we evaluated 112 ECMO cannulas from 58 patients for microbial colonization using sonication fluid culture & 16S-rRNA-PCR (n = 105), or roll plate method (n = 7). 38 (33.9%) cannulas from 30 (51.7%) patients showed evidence for bacterial colonization with the predominance of coagulase-negative staphylococci (67.4%). Antipseudomonal β-Lactam treatment at cannulation and ECMO initiation at referring hospitals were associated with cannula colonization upon multivariable per-patient analysis. The prevalence of bloodstream infections was equally low and the occurrence of fever after and number of anti-infective drugs given during ECMO therapy was similar in patients with and without exposure to colonized cannulas. Finally, there was no association of cannula colonization with adverse outcomes. In summary, our data suggest that bacterial ECMO cannula colonization does not affect the clinical course of patients and thus discourage routine microbial assessment of cannula tips or even cannula exchange in the absence of clinical signs of cannula infection.
