Transfusion rates in oral and maxillofacial surgery and their influencing factors in the context of patient blood management.
Article in Clinical oral investigations, 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
objectivesExisting evidence on transfusion requirements in oral and maxillofacial surgery (OMFS) is limited to selected indications. This study aimed to provide an overview of transfusion rates across the full diagnostic spectrum and to identify factors influencing transfusion rates with relevance for patient blood management (PBM). MATERIALS AND
methodsAll operated OMFS patients from a five-year period (n = 13,239) were retrospectively analyzed. Diagnosis-specific transfusion rates were determined, followed by a subgroup analysis of free flap surgeries. Logistic regressions identified factors influencing transfusion rates. ROC analysis in the free flap subgroup determined preoperative hemoglobin cut-off values for increased transfusion risk. Differences in treatment course associated with preoperative anemia were assessed.
resultsOverall transfusion rate was 5.1%. Microvascular free flap surgery was the primary driver of transfusion with a rate of 58.8%, independent of underlying pathologies. Non-oncologic indications requiring free flap reconstruction showed high transfusion rates similar to oncologic indications, whereas the same diagnoses without free flaps had rates < 5%. Free flap reconstruction (OR 5.21) and preoperative anemia (OR 6.25) were the strongest factors influencing transfusion rates. ROC analysis identified preoperative hemoglobin of 12.25 g/dl as risk threshold for intraoperative transfusion. Preoperative anemia was associated with a less favorable course regarding intensive care unit treatment, in-hospital mortality and hospital length of stay.
conclusionsTransfusion rates in OMFS are generally low but increased in reconstructive free flap surgery. CLINICAL RELEVANCE: These findings offer an evidence base for targeted PBM strategies, including early identification and treatment of preoperative anemia, like intravenous iron therapy in free flap patients, and transfusion rate-adapted blood product preparation to improve perioperative management.
