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
Ischemic stroke often results in high mortality and significant disability. Current research primarily focuses on understanding neuroinflammation and cell death following a stroke to identify novel therapeutic targets. This study investigates the endothelial cell-specific role of Thioredoxin interacting protein (TXNIP) in ischemic stroke and its underlying molecular mechanisms both in vitro and in vivo. By targeting endothelial cells, we aim to determine how TXNIP knockdown promotes neuroprotection, enhances angiogenesis, and reduces inflammation post-stroke. In vitro, an oxygen-glucose deprivation (OGD) model using bEnd.3 cells simulated ischemic conditions. Cellular injury was evaluated through cell proliferation and angiogenesis assays, while dual immunofluorescence staining assessed ZO-1 and CD31 expression. Western blotting measured protein levels of TXNIP, nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3), ASC, pro-caspase-1, and interleukin-1β (IL-1β). In vivo, a middle cerebral artery occlusion (MCAO) mouse model was employed to mimic ischemic stroke. Brain injury was evaluated using triphenyl tetrazolium chloride (TTC) and Nissl staining, and molecular changes in injury markers were assessed via Western blot analysis. In vitro, TXNIP knockdown promoted cell proliferation and angiogenesis, reduced inflammation, and decreased ZO-1 and CD31 fluorescence intensity. TXNIP knockdown also reversed OGD-induced upregulation of TXNIP, NLRP3, ASC, pro-caspase-1, and IL-1β. In vivo, TXNIP knockdown improved neurological recovery, reflected by lower Longa scores, increased Nissl body presence, and reduced infarct size. These findings suggest that TXNIP knockdown mitigates inflammation, enhances angiogenesis, and reduces cerebral damage following ischemic stroke. This provides valuable insights into potential endothelial cell-specific therapeutic strategies for stroke treatment.
