Association of Body Mass Index with 28-Day Mortality in Adult Intensive Care Patients with Sepsis: A Retrospective Observational Study.

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
Objectives: The effect of obesity on sepsis outcomes remains controversial. Several studies have described an "obesity paradox," whereby a higher body mass index (BMI) correlates with improved survival in critically ill patients. This study aimed to investigate the relationship between BMI and 28-day mortality in adult patients with sepsis admitted to the intensive care unit (ICU). Methods: We conducted a retrospective observational study including 83 adult patients diagnosed with sepsis according to the Sepsis-3 criteria who were admitted to the ICUs of Şişli Hamidiye Etfal Training and Research Hospital between June 2023 and June 2025. BMI was reported using World Health Organization categories and analyzed using three BMI groups based on the final cohort distribution. The primary endpoint was 28-day mortality. Multivariable logistic regression analysis was conducted with adjustment for age, sex, Sequential Organ Failure Assessment score, creatinine, and C-reactive protein. Results: The median age was 75 years (interquartile range, 66-82), and 55% of the patients were male. Survivors had a higher BMI than non-survivors (27.3 vs. 24.9 kg/m Conclusion: Higher BMI was associated with lower 28-day mortality in septic ICU patients. Further prospective studies are needed to validate this relationship and explore the underlying potential mechanisms.
