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: To analyse the changes in serum superoxide dismutase (SOD), malondialdehyde (MDA), IL-6, IL-8, TNF-a, and serum immune markers in patients with gastrointestinal bleeding (GIB) after allogeneic blood transfusion (ABT) during surgery. Methods: 80 patients with GIB requiring surgical treatment were enrolled. The experimental group (EG, n=40) received 2-4 U of red blood cells during surgery, while the control group (CG, n=40) did not. T cell subsets, natural killer cells (N KC), immunoglobulin, serum inflammatory factors, platelet count, oxidative stress indicators, and hemostasis time were measured before and 1 day after ABT. Results: In the EG, NKC, CD 3+, CD 4+, and CD 4+/CD8+ decreased, IgG decreased, IL-6, IL-8, and TNF-a increased 1 day after ABT, while IgA, IgM, and platelet count remained unchanged. The EG showed a tremendous increase in SOD, a more significant decrease in MDA, and shorter hemostasis time and time for occult blood to become negative compared to the CG. Conclusions: ABT was effective in treating GIB but had an inhibitory effect on immune function. ABT did not affect platelet function but significantly changed oxidative stress indicators, inhibiting the peroxide response in GIB patients.
