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
Cerebral ischemia, a major cause of death and disability worldwide, results from restricted cerebral blood flow leading to neuronal damage. Despite the availability of thrombolytic and mechanical interventions, their limited therapeutic window and high cost necessitate exploration of affordable, multi-target neuroprotective strategies. Albizia procera (Roxb.) Benth., a medicinal plant rich in flavonoids and saponins, has been traditionally used for its anti-inflammatory and antioxidant properties. The present study evaluated the neuroprotective potential of the ethanolic extract of Albizia procera leaves (APL) against global cerebral ischemia-reperfusion injury (GCIRI) in rats. Adult male Wistar rats underwent bilateral common carotid artery occlusion followed by reperfusion (BCCAO/R) and received APL (100, 200, or 400 mg/kg, p.o.) or quercetin (25 mg/kg, p.o.) for 14 consecutive days before ischemia induction. Neurological, behavioural, biochemical, and histopathological parameters were assessed to determine neuroprotection. Pretreatment with APL significantly reduced infarct size and brain edema, improved neurological and sensorimotor functions, and restored behavioral performance in ischemic rats. APL also attenuated oxidative stress by reducing lipid peroxidation (MDA) and enhancing antioxidant enzyme activities (SOD, CAT, and GSH). Furthermore, it markedly decreased proinflammatory cytokines (TNF-α, IL-1β), indicating suppression of neuroinflammation. Histopathological analysis revealed that APL preserved hippocampal neuronal integrity and reduced pyknosis and vacuolation in a dose-dependent manner. The highest neuroprotective efficacy was observed at 400 mg/kg, comparable to quercetin. These findings suggest that Albizia procera exerts significant neuroprotection by mitigating oxidative stress and inflammation, possibly via modulation of the PI3K/Akt/NF-κB signaling pathway, and may serve as a promising phytotherapeutic candidate for ischemic stroke management.
