1 · What the graph read from it

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.

2 · The registry

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: Excessive neuroinflammation mediates blood-brain barrier (BBB) disruption and poor outcomes after acute ischemic stroke (AIS). Cyclophilin A (CypA), when released into the extracellular space (designated as eCypA), may participate in inflammatory reactions and vascular dysfunction. However, its role in regulating neuroinflammation and BBB injury in AIS, as well as the therapeutic potential of targeting eCypA remain unclear. Methods: ELISA was used to detect eCypA release in serum from 22 AIS patients (17 mild, 5 severe; 13 males, 9 females; mild: age 65.41 ± 10.20 years, NIHSS 2.88 ± 1.45; severe: age 64.00 ± 5.04 years, NIHSS 9.40 ± 3.29; blood sampled within 48 h of onset), in serum/cerebrospinal fluid (CSF) from transient middle cerebral artery occlusion (tMCAO) rats, and in supernatants from BV2 (microglia) or bEnd.3 (brain microvascular endothelial cells) exposed to oxygen-glucose deprivation/reoxygenation (OGD/R) or lipopolysaccharide (LPS). Nine-week-old male Sprague-Dawley rats ( Results: eCypA levels were significantly elevated in AIS patient serum (1.74 ± 0.23 ng/mL in mild, 2.39 ± 0.09 ng/mL in severe vs. 1.30 ± 0.19 ng/mL in healthy controls, Conclusion: eCypA, released by microglia and brain microvascular endothelial cells under ischemic-hypoxic and inflammatory conditions, serves as a critical pathogenic mediator that drives neuroinflammation and BBB disruption in AIS. Targeting eCypA with C46 peptide effectively abrogates these pathological cascades, thereby supporting eCypA as a novel therapeutic target for AIS.
