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 and purposeOur aim was to analyze factors that influence transfusion requirements in surgical patients in order to achieve a transfusion-saving strategy.
methodsData was collected from patient's files at the Notre Dame de Secours-Jbeil University Hospital Center between January 2017 and June 2019. Selection was made for 400 patients who had undergone surgery and required transfusion. The studied variables were age, sex, and type of surgery whether planned or urgent with its expected level of bleeding. The presence of chronic anemia, coronary artery disease, values of hemoglobin and hematocrit before and after transfusion, iron status preoperatively, and post-operation complications were also noted.
resultsThe analysis of 400 transfused surgical patients showed that the mean age was 62 ± 18 years with 52.5% women and 47.5% men. In 82.3% of patients, surgical bleeding was expected, 77.8% of surgeries were scheduled, and 22.3% were urgent. Fifty-two percent of patients were known to have coronary artery disease. Orthopedic (35%) and cardiothoracic (29.5%) surgeries had the highest transfusion rate. Among all patients, only 106 patients (26.5%) underwent a preoperative iron workup. The pre-transfusion levels of hemoglobin were 9.9 ± 0.6 and hematocrit of 29.7 ± 1.9. 26.3% of patients had a post-transfusion complication. On the other hand, 19.5% of women and 20% of men were already anemic when admitted to the hospital. Anemic women required 7.6 times more transfusions than non-anemic, while anemic men required 12.38 times more transfusions than non-anemic men. Age, presence of coronary artery disease, and chronic anemia have been found to be factors increasing the risk of post-transfusion complications. Finally, urgent and unplanned surgeries are 2.9 times more likely to cause post-transfusion complications.
conclusionThis study therefore confirms that anemic patients are more likely to receive perioperative blood transfusions. Consequently, in order to reduce blood transfusion and its complications, it would be beneficial primarily to diagnose and treat anemia preoperatively. Other transfusion-saving strategies could also be useful in the setting of surgical bleeding, such as the use of tranexamic acid and different autologous transfusion methods like the cell saver.
