Effects of hemoglobin transfusion thresholds on clinical outcomes in sepsis-related ARDS: A retrospective cohort analysis utilizing the MIMIC-IV database.
Observational study in Medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Sepsis, a systemic pathological reaction induced by infection, is a major contributor to acute respiratory distress syndrome (ARDS) in intensive care units (ICUs). This retrospective cohort study aimed to evaluate the impact of hemoglobin transfusion thresholds on clinical outcomes in patients with sepsis-related ARDS using the medical information mart for intensive care IV database. Patients were categorized into a high-threshold group (hemoglobin ≥ 7 g/dL) and a low-threshold group (hemoglobin < 7 g/dL) based on the lowest hemoglobin concentration within 24 hours before transfusion. The results showed no significant differences in overall mortality during hospitalization, in the ICU, or at 30, 60, and 90 days between the high- and low-transfusion threshold groups. The duration of ICU stay was comparable in both groups; however, the total hospital stay was longer in the low-threshold cohort. Stratified analysis showed that changing the transfusion thresholds did not significantly affect the prognosis of people with ARDS stage 1. However, in ARDS stage 2, the high-threshold group showed a trend toward lower in-hospital and ICU mortality rates, although the difference was not statistically significant. This study suggests that a low-transfusion threshold does not adversely affect sepsis-related ARDS patient mortality, but the potential benefits of blood transfusion need to be balanced against the risk of prolonged hospitalization.
