Microbiological and clinical predictors of sepsis-associated encephalopathy in bloodstream infections: a retrospective cohort study.
Article in Frontiers in cellular and infection microbiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled 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.
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: Sepsis-associated encephalopathy (SAE) is a common and severe complication of sepsis, significantly contributing to morbidity and mortality. The impact of specific blood-borne pathogens on SAE risk and prognosis remains unclear. This study investigates the microbiological and clinical factors associated with bloodstream infection-induced SAE. Methods: We analyzed data from the MIMIC-IV database, including 16,141 sepsis patients who met inclusion criteria. Patients were divided into SAE and non-SAE groups for comparison. Multivariate regression identified independent risk factors for SAE and associated outcomes, including in-hospital mortality. Results: Coagulase-negative staphylococci (CoNS) was identified as a key microbial risk factor for SAE (HR=1.919, P<0.001), though it was not associated with in-hospital mortality. Higher SOFA scores, mechanical ventilation, and prolonged antibiotic use significantly increased SAE risk. Laboratory tests revealed higher white blood cell counts, platelet levels, and metabolic abnormalities in SAE patients. Methicillin-resistant Staphylococcus aureus (MRSA) was linked to increased mortality in SAE patients (HR=3.423, P<0.001). Conclusion: Coagulase-negative staphylococci is a significant risk factor for SAE development, but not for mortality. Advanced age, female gender, higher SOFA scores, and mechanical ventilation further contribute to SAE risk. Early identification and targeted management of pathogens, particularly methicillin-resistant Staphylococcus aureus, are crucial for improving SAE outcomes.
