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
This study investigates whether remodeling/enhancing the two vital proteins-hemoglobin and B3p-in erythrocytes with artificial interference can rejuvenate aged and damaged erythrocytes. Using Raman spectroscopy and SDS measurement, the study demonstrated that certain flavonoids, such as Hydroxysafflor Yellow A, could remodel/enhance the two proteins and restore their conformation, content, and distribution in aged erythrocytes within a few hours. As a result, it led to a restoration of nearly all cellular and molecular properties of old erythrocytes aged 90-120 days and cells stored under blood bank conditions for 21 days. The flavonoids could even recover erythrocytes of α/β-thalassemia. Moreover, pre-incubating the cells with flavonoids can prevent aging and damage caused by mechanical injury, hypoxic stress, acid-base imbalances, and storage lesions, with protective effects lasting for at least 21 days. In summary, this research reveals for the first time that remodeling hemoglobin and B3p with flavonoids is a promising intervention to enhance the longevity and resilience of erythrocytes against damage. It holds significant implications for biomedicine, including blood storage, the production of blood products, disease treatment, and high-altitude medicine related to hypoxic physiology.
