Association between early enteral nutrition and 28-Day mortality in mechanically ventilated patients with sepsis: a retrospective analysis of the MIMIC-IV database.
Observational study in BMC infectious diseases, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundThe optimal timing of enteral nutrition for critically ill septic patients in the intensive care unit (ICU) who require invasive mechanical ventilation has not been determined, and the influence of early enteral nutrition on clinical outcomes is unclear.
methodsThis retrospective observational study utilized data from the Medical Information Mart for Intensive Care IV 2.2 (MIMIC-IV 2.2) database to investigate patients with sepsis who needed invasive mechanical ventilation post-ICU admission. Patients who had enteral nutrition (EN) initiated within 72 h of ICU were categorized into the early enteral nutrition (EEN) group, while those who began enteral nutrition after 72 h were placed in the delayed enteral nutrition (DEN) group. Propensity score matching analysis was performed to compare outcomes between these two groups, with the primary outcome being 28-day mortality.
resultsThe final analysis included 2293 patients, 1546 (67.4%) of whom received enteral nutrition within 72 h of invasive mechanical ventilation. The overall 28-day mortality rate was 31.0%. After propensity score matching employing the proximity matching method, Cox survival analysis revealed that early enteral nutrition was associated with increased 28-day mortality in septic patients on invasive mechanical ventilation (hazard ratio(HR) 1.440, 95% CI 1.179-1.760; p < 0.001). The sensitivity and robustness of the evaluation results under different models, including optimal matching (adjusted odds ratio (aOR) 1.52, 95% CI 1.21-1.92, p < 0.001), inverse probability of treatment weighting (aOR 1.27, 95% CI 1.02-1.58, p = 0.034), and logistic regression analysis (aOR 1.48, 95% CI 1.18-1.84, p = 0.001), confirmed the association between early enteral nutrition and increased 28-day mortality in mechanically ventilated septic patients.
conclusionsCompared to delayed enteral nutrition, early enteral nutrition is associated with higher 28-day mortality in septic patients on invasive mechanical ventilation. Randomized controlled trials are warranted to validate these findings.
