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
Ferroptosis plays a crucial role in the secondary pathophysiological damage to brain tissue surrounding hematomas after intracerebral hemorrhage (ICH). While platelet factor 4 (PF4) is known to promote regeneration following peripheral nerve injury, its role in brain tissue repair after cerebral hemorrhage remains unclear. In this study, Hemin-induced PC12 cells were treated with various inhibitors and assessed for viability, oxidative stress, and ferroptosis using a combination of assays, including CCK-8 (Cell Counting Kit-8), EdU (5-Ethynyl-2'-deoxyuridine), flow cytometry, and immunofluorescence. ICH cells were also treated with recombinant PF4 (Rm-PF4) and a CXCR3 antagonist (AMG487) to investigate the mechanism by which Rm-PF4 influences Hemin-induced PC12 cell injury and inflammation. Subsequently, ICH mouse models were established via collagenase injection. Neurological function in these mice was evaluated using the Cylinder and Corner tests. Histopathological damage to brain tissue was analyzed through HE, TUNEL, and Nissl staining, as well as immunohistochemistry, to further explore the role of Rm-PF4 in controlling neuroinflammation in vivo. Results showed that Rm-PF4 inhibited Hemin-mediated ferroptosis-induced PC12 cell damage and inflammation by activating the CXCR3/AKT1/SLC7A11 signaling pathway. Blocking the CXCR3/AKT1/SLC7A11 pathway partially reversed PF4's protective effects on Hemin-induced PC12 cells.In ICH mice, pro-inflammatory marker CD16 (3rd day) and anti-inflammatory marker Arg1 (7th day) were significantly decreased and increased, respectively (p<0.05). IL-6, TNF-α, and IL-1β levels were down-regulated in brain tissues after Rm-PF4 injection, which was significantly reversed by AMG487. PF4 inhibits ferroptosis after ICH reduced PC12 cell damage and the inflammatory response via activating the CXCR3/AKT1/SLC7A11 pathway.
