Factors Affecting Transfusion Rate for Patients After Hip Fracture.
Article in Orthopedic reviews, 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
Background: Hip fractures are a common indication for red blood cell transfusion among elderly patients. Blood transfusion may be clinically necessary, yet it carries risks and should be anticipated according to patient and surgical characteristics. Objective: This retrospective study aimed to identify clinical and perioperative factors associated with the need for blood transfusion among patients hospitalized with hip fracture. Methods: The study included 150 patients with hip fracture treated at the Orthopedic Department of Bnei Zion Medical Center between April 2014 and June 2015. The transfusion group included 100 patients who received blood transfusions, and the control group included 50 surgically treated patients who did not require transfusion. Group comparisons were performed using t tests, chi-square tests, Fisher exact tests, and multivariable logistic regression. Results: Transfused patients were older than non-transfused controls (84.5 ± 7.4 vs 80.2 ± 8.1 years; P = 0.002). Age above 90 years (34% vs 14%; P = 0.030), subtrochanteric fracture (20% vs 6%; P = 0.031), aspirin use (41% vs 18%; P = 0.006), surgery duration exceeding 90 minutes (33% vs 8%; P = 0.0079), and B+ blood type (26% vs 6%; P = 0.041) were significantly associated with transfusion in univariate analysis. In multivariable logistic regression, age above 90 years (OR, 2.64; 95% CI, 1.08-6.45; P = 0.033), subtrochanteric fracture (OR, 3.21; 95% CI, 1.01-10.18; P = 0.048), and surgery duration exceeding 90 minutes (OR, 4.87; 95% CI, 1.62-14.63; P = 0.005) remained significant predictors. Conclusions: Among elderly patients with hip fracture, advanced age, subtrochanteric fracture, and prolonged surgical duration were the main independent predictors of blood transfusion. Aspirin use and B+ blood type were significant in univariate analysis but should be interpreted cautiously. Recognition of high-risk profiles may improve perioperative planning, blood bank preparation, and patient management.
