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

backgroundThe Rosemary extract (RE) possesses various antioxidant, cytoprotective and cognition- improving bioactivities. In this study, we postulated which doses of RE have a more effect on the hippocampus of middle-aged rats.

methodsIn this experimental study, thirty-two middle-aged male Wistar rats were fed by different doses (50,100 and 200 mg/kg/day) of RE (containing 40% carnosic acid) or distilled water for 12 weeks. The effects of different RE doses on learning and spatial memory scores, hippocampal neuronal survival, antioxidant enzymes and lipid peroxidation amount were evaluated by one and two way analysis of variance (ANOVA).

resultsIt seemed that RE (100mg/kg) could recover the spatial memory retrieval score (p< 0.05). The amount of activity of SOD, GPx and CAT enzymes in the hippocampus of animals of the RE (100mg/kg) group showed a significant increase compared to the normal group (p< 0.01), (p< 0.01) and (p< 0.05), respectively. Also, the amount of activity of GPx in the RE (50 mg/kg) group of animals showed a significant increase compared to the normal group (p< 0.05). No significant difference was found between the groups in the MDA level.

conclusionThe results revealed that rosemary extract (40% carnosic acid) may improve the memory score and oxidative stress activity in middle aged rats in a dose dependent manner, especially in 100mg/kg.
