Neuroprotection by Resveratrol in Chronic Cerebral Hypoperfusion: A Study on Synaptogenesis Enhancement and Apoptosis Inhibition.
Article in Iranian journal of pharmaceutical research : IJPR. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Background: Chronic cerebral hypoperfusion (CCH) is a key contributor to vascular dementia (VaD) and Alzheimer's disease. Resveratrol (RSV), a polyphenol with potential neuroprotective properties, may mitigate CCH-induced neuronal damage, but its mechanisms remain unclear. Objectives: This study investigated RSV's effects on memory enhancement through synaptogenesis and apoptosis inhibition in the hippocampus in a rat CCH model. Methods: Forty male rats were randomly divided into four groups: Sham, 2-VO (bilateral carotid artery occlusion), 2-VO+RSV (2.5 mg/kg), and 2-VO+RSV (5 mg/kg). Initial group sizes (n = 10 each) were maintained by replacing deceased animals (2-VO: 7, 2-VO+RSV2.5: 4, 2-VO+RSV5: 6 deaths). The RSV was administered via intraperitoneal injection (ip) for 35 days post-surgery. Cognitive function was assessed using Morris water maze (MWM) and shuttle box tests. Hippocampal mRNA/protein levels of B-cell lymphoma 2-associated X (Bax), B-cell lymphoma 2 (Bcl-2), Caspase-3, Ras homolog family member A (RhoA), Rho-associated coiled-coil containing protein kinase 2 (ROCK2), calcium/calmodulin-dependent protein kinase II alpha (CaMKII-α), and N-methyl-D-aspartate receptor subunit 2B (NMDAR2B) were measured. Results: The RSV (5 mg/kg) significantly improved spatial memory in the MWM. Also, RSV at doses of 2.5 and 5 mg/kg significantly increased the entrance latency to the dark compartment (P < 0.05 and P < 0.01 vs 2-VO, respectively). There was a downregulation of pro-apoptotic markers (Bax, Caspase-3) and Rho/ROCK gene expressions, and an upregulation of anti-apoptotic Bcl-2 gene expression and synaptic proteins (CaMKII-α, NMDAR2B) after RSV treatment. The RSV at 5 mg/kg significantly reduced the Bax/Bcl-2 ratio compared to the 2-VO group. Conclusions: The RSV protects against CCH-induced neuronal damage by inhibiting apoptosis and enhancing synaptic plasticity. These findings highlight RSV's therapeutic potential for vascular cognitive impairment.
