The Influence of Older Age on RBC Transfusion Decisions in ICU Patients.
Observational study in Critical care medicine, 2026. 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
objectivesRBC transfusions are common in the ICU. Recent studies suggest that a restrictive transfusion policy is noninferior or superior to a liberal policy. However, few studies focus on the influence of age in transfusion. In elderly ICU patients, reduced physiologic reserves may shift the perceived risk-benefit balance of transfusion, potentially leading to different transfusion practices. This study examines whether transfusion practices in ICU patients differ across patient age.
designThis is a substudy of the International Point Prevalence Study of ICU Transfusion Practices (InPUT), a global, multicenter, prospective observational cohort study.
settingICUs from 233 centers across 30 countries. Data were collected from March 2019 to October 2022 in prespecified weeks. PATIENTS: Adult ICU patients (≥ 18 yr) admitted during predefined study weeks. Patients were categorized by age (< 65, 65-75, 75-85, and > 85 yr).
interventionsNone. MEASUREMENTS AND MAIN
resultsA total of 3643 patients from 233 centers across 30 countries were included. Of these, 53% were younger than 65 years, 26% were 65-75 years, 17% were 75-85 years, and 4% were older than 85 years. RBC transfusion rates ranged from 23% to 26% across all age groups ( p = 0.91). Patients older than 85 years had higher stated hemoglobin thresholds (median, 10.0 g/dL) compared with younger patients (median, 8.0 g/dL; p < 0.001). "Age" and "improve general state" were more frequently cited as reasons for transfusion in patients older than 85 years. However, after adjustment, age was not associated with the probability of receiving an RBC transfusion.
conclusionsDifferent transfusion strategies are applied in patients older than 85 years old. These differences appear to be driven by age-related differences in physiology and diagnoses rather than motivated by older age itself.
