Are elderly patients undergoing blood transfusion during hip fracture surgery at risk of postoperative delirium: a retrospective observational study.
Article in Musculoskeletal surgery, 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
purposeDelirium is common following hip fracture surgery. Red blood cell transfusion (RBCT), which is frequently needed in this population, has been inconsistently associated with incident delirium in previous studies. This study aims to investigate whether RBCT in patients undergoing hip fracture surgery is associated with increased risk of post-operative delirium, and to identify potential risk factors that might influence this association. MATERIALS AND
methodsWe conducted a retrospective observational study of all hip fracture patients who underwent surgery between November 1 2020 and February 28 2022. Delirium was diagnosed based on DSM V criteria, and assessed daily. The need of perioperative RBCT, and the number of units transfused, were recorded.
resultsA total of 364 participants with a mean age of 84 years were included. Delirium was recorded in 49 (14%) patients, while 88 (24%) required RBCT. In logistic regression, RBCT was associated with delirium (OR = 3.88, 95% CI = 1.23-12.24), after adjusting. An increasing number of RB units transfused was associated with increased probability of delirium (P for linear trend = .013).
conclusionsClinicians should carefully consider the indications for RBCT in hip fracture patients. Further studies are needed to confirm these results, and to investigate the potential mechanisms underlying this association.
