Determining the Optimal Parameters for Scoring Systems to Predict Postoperative Bleeding After Diabetic Coronary Artery Bypass Surgery.
Article in Brazilian journal of cardiovascular 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
introductionPostoperative bleeding increases morbidity and mortality. We aimed to review the scoring systems used to predict massive bleeding after isolated coronary artery bypass grafting in diabetic patients and determine the parameters of the new scoring system - the Optimum Risk Score for Bleeding (ORS).
methodsTwo hundred ninety-seven diabetic patients who underwent isolated coronary artery bypass operation between 2017 and 2019 were reviewed. The patients were grouped according to amount of drainage (> 850 mL/day) and the European Multicenter Study on Coronary Artery Bypass Grafting (E-CABG) bleeding severity grade. Previously identified risk factors and scoring systems (Papworth, WILL-BLEED, Association of Cardiothoracic Anesthetists perioperative risk of blood transfusion [ACTA-PORT], Transfusion Risk and Clinical Knowledge [TRACK], and Transfusion Risk Understanding Scoring Tool [TRUST]) were analyzed.
resultsPapworth was better predictive for E-CABG bleeding grades 2 - 3. WILL-BLEED, ACTA-PORT, TRACK, and TRUST had no discriminatory value in terms of E-CABG bleeding grades 2 - 3. Among the parameters in the scoring systems, gender, preoperative hemoglobin (or hematocrit) value, preoperative platelet count, use of antiplatelets until less than five days prior to the operation, and preoperative creatinine (or estimated glomerular filtration rate) values should be included in the scoring system we aim to establish in the future, the ORS.
conclusionThe current scoring systems do not provide satisfactory results in predicting postoperative bleeding. Female gender, lower body mass index, and preoperative platelet count were associated with increased postoperative bleeding. There is a need for an ORS which gives more precise results in predicting postoperative bleeding.
