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: It is essential to maintain the quality of the stored blood, because various factors affect the stored red blood cells (RBCs) over time, some red blood cell storage lesions (RCSL) develop during storage, and it could reduce the function of the RBCs. The present study aimed to evaluate the effects of glutathione monoethyl ester on different biochemical changes, oxidant, and antioxidant levels in the leukoreduced RBCs (LR-RBCs) during storage. Materials and Methods: About 10 units of LR-RBC were collected, processed and stored according to the standard operating procedures (SOPs) of the Iranian Blood Transfusion Organization. Each unit divided into 2 equal parts; LR-RBC treated with glutathione monoethyl ester and a control group. Exposure of phosphatidylserine (PS), reactive oxygen species (ROS) and microvesicle derived from the RBCs (RBC-MVs), were measured by the flow cytometry method. ELISA was used to measure the level of glutathione, and 2, 3-diphosphoglycerate (2,3-DPG). Glucose-6-phosphate dehydrogenase (G6PD) enzyme activity was measured with a chemistry autoanalyzer. Results: The levels of glutathione reduced the initial value in the treated group (80%), and the control group (60%), respectively. Exposure of surface PS, ROS and RBC-MVs increased significantly during storage time for consecutive weeks to the amount of GSH. The levels of 2,3-DPG decreased with increasing storage time. Conclusions: Overall, The study suggest that glutathione monoethyl ester is effective to reduce the oxidative stress and the quality of RBCs can be improved.
