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
Objectives: To investigate the protective effect and underlying mechanism of Lanzhou Lily Polysaccharide (LP) against radiation-induced splenic damage in mice. Methods: Mice were pretreated with LP before X-ray irradiation. (1) Antioxidant enzyme activities (superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx)), glutathione (GSH) content, and levels of malondialdehyde (MDA), myeloperoxidase (MPO) in mice serum were measured using commercial kits; (2) The spleen index was calculated; (3) Hematoxylin-eosin (H&E) staining was performed to observe spleen morphology; (4) Splenocyte apoptosis and DNA damage were detected; (5) Immunohistochemistry and Western blotting were employed to detect DNA damage repair (eg, γ-H2AX) and apoptosis-related protein expression in splenic tissues. Results: LP pretreatment alleviated irradiation-induced impairment of antioxidant capacity in mice, increased SOD, CAT, GPx activities and GSH content, decreased MDA and MPO levels. It reversed irradiation-induced reduction in spleen index. H&E staining showed LP mitigated radiation-caused splenic morphological damage. TUNEL assay demonstrated LP lowered the splenocyte apoptosis rate. Comet assay confirmed LP inhibited radiation-induced DNA damage in splenocytes. Immunohistochemistry and Western blotting results revealed LP down-regulated the expression of γ-H2AX and modulated DNA damage repair-related proteins, regulating apoptosis-related protein levels. Conclusion: LP can protect mice from radiation-induced splenic damage.
