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

introductionCerebral ischemic strokes cause brain damage, primarily through inflammatory factors. One of the regions most affected by middle cerebral artery occlusion (MCAO) is the hippocampus, specifically the CA1 area, which is highly susceptible to ischemia. Previous studies have demonstrated the anti-inflammatory properties of quercetin. Therefore, this study aimed to investigate the neuroprotective effects of quercetin on hippocampal CA1 neurons following MCAO. MATERIALS AND

methodsFifty-six male Albino Wistar rats were divided into seven groups (intact, sham, stroke, vehicle, and three quercetin-treated groups receiving 5, 10, and 20 mg/kg, respectively), each containing 8 rats. Various assessments, including brain water content, the rotarod test, the Bederson neurological score, the Morris water maze (MWM) test, the shuttle box test, histopathological evaluations, and measurements of interleukin-10 (IL-10) and interleukin-1β (IL-1β) levels, were conducted across the groups.

resultsCompared with control rats, 5 and 10 mg/kg quercetin-treated rats presented significant improvements in brain water content, neurological function, and motor function and improved performance in the MWM and shuttle box tests. Histopathological analyses revealed better preservation of CA1 neurons in these groups. Additionally, IL-10 levels significantly increased, whereas IL-1β levels significantly decreased. However, the group receiving 20 mg/kg quercetin showed no statistically significant changes in the parameters assessed (P > 0.05).

conclusionQuercetin may help prevent or ameliorate brain injuries caused by acute stroke, suggesting its neuroprotective effects. The reduction in IL-1β and increase in IL-10 may play key roles in quercetin's protective mechanism.
