Perioperative transfusion rates and efficiency in thoracic surgery: toward rational transfusion strategies.
Article in Journal of cardiothoracic 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
objectiveTo evaluate perioperative blood transfusion requirements, transfusion-related risk factors, and blood utilization efficiency in thoracic surgery, and to establish procedure-specific recommendations for the Maximum Surgical Blood Ordering Schedule (MSBOS). MATERIALS AND
methodsA retrospective analysis was conducted on 2,062 patients who underwent thoracic surgery at a single center between January 2022 and June 2024. Demographic characteristics, comorbidities, surgical techniques, perioperative transfusion requirements, and clinical outcomes were analyzed. Transfusion efficiency was assessed using the Transfusion Index (TI), Transfusion Percentage (%T), and Crossmatch-to-Transfusion Ratio (C/T). MSBOS recommendations were derived based on these metrics.
resultsPerioperative transfusion was required in 15.1% of patients, while 8.0% received intraoperative transfusions. Transfusion need was significantly associated with advanced age, lower preoperative hemoglobin levels, longer anesthesia duration, thoracotomy, decortication, and pneumonectomy. Patients who received intraoperative transfusions had significantly higher complication and mortality rates. Overall transfusion efficiency was low (TI: 0.27; %T: 15%), indicating substantial over-preparation of blood products.
conclusionRoutine preoperative blood preparation is unnecessary for many thoracic surgery procedures. A procedure-specific MSBOS or a "type-and-screen" strategy appears sufficient for most interventions, except for decortication and pneumonectomy. Tailored patient blood management strategies, including procedure-specific MSBOS implementation, may substantially improve resource utilization and patient outcomes.
