Monocyte Anisocytosis Can Discriminate Between Sepsis and Sterile Inflammation, but not Mortality, in Critically Ill Surgical/Trauma Patients: A Secondary Prospective Analysis.
Observational study in Critical care explorations, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundMonocyte anisocytosis (monocyte distribution width [MDW]) has been previously validated to predict sepsis and outcome in patients presenting in the emergency department and mixed-population ICUs. Determining sepsis in a critically ill surgical/trauma population is often difficult due to concomitant inflammation and stress. We examined whether MDW could identify sepsis among patients admitted to a surgical/trauma ICU and predict clinical outcome.
designSecondary analysis of three prospective observational clinical studies.
settingSingle institution ICU. PATIENTS/SUBJECTS: Two hundred thirty-eight participants were included in this study: 107 patients who were admitted to the ICU and adjudicated to have sepsis, 80 patients who were considered critically ill nonseptic (CINS), and 51 healthy control participants.
interventionsMDW was measured among hospitalized patients admitted to the ICU with the diagnosis of sepsis or CINS patients at risk of developing sepsis. Blood samples were collected at admission and at intervals during ICU admission. MEASUREMENTS AND MAIN
resultsMDW significantly differed between septic and CINS patients on ICU admission (26.4, interquartile range [IQR, 23.5-30.8] vs. 20.1 [IQR, 17.9-21.9]; p < 0.001) and could discriminate with an area under the receiver operating characteristic curve of 0.85 (95% CI, 0.79-0.91; p < 0.001). An MDW of greater than 22.0 at admission to the ICU could identify sepsis with a 78% specificity and a 90% sensitivity but could not discriminate in-hospital, 30-day, or 90-day mortality. LIMITATIONS: Small sample size from a single institution. Our analysis did not include other relevant biomarkers such as procalcitonin, C-reactive protein, and interleukin-6. In the imputation of missing values, linear mixed-effect models were used, risking model misspecification and the violation of the missing-at-random assumption.
conclusionsAmong surgical/trauma ICU patients, MDW can discriminate between sepsis and nonseptic inflammation, but it is a weak predictor of mortality.
