Dietary supplements for prevention of Alzheimer's disease:

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
Objectives: Alzheimer's disease (AD) is one of the most common neurodegenerative diseases in people over 65. The present research aimed to investigate the potential of different dietary supplements (DS) in preventing AD in an experimental animal model and Materials and Methods: Three DS containing a mixture of wheat-germ oil and black pepper extract/or turmeric extract were prepared. Total phenolic content, HPLC-phenolic profile, phytosterols content, fatty-acids profile, and anti-oxidant activity were evaluated in all DS. The protective effect of the prepared DS was assessed through their impact on cholinergic neurotransmission and the gene expression of GSK3β, APP, and Akt. Oxidative stress and inflammatory markers were evaluated. The inhibition activities against acetylcholinesterase (AChE) and reduction of amyloid-β aggregation of the major phytochemicals present in the studied DS were evaluated using Results: Molecular docking revealed that rosmarinic acid and β-Sitosterol exhibited the strongest binding affinities for AChE and Amyloid-β, respectively. The results showed that all DS reduced cholinergic neurotransmission, decreased TNF-α as an inflammatory marker, and improved oxidative stress status. All DS down-regulated the expression of GSK3β and APP while significantly up-regulating the expression of the Akt gene. Conclusion: The present study concluded that all DS enhanced cholinergic neurotransmission, reduced inflammation, and improved oxidative stress status by impacting the expression of GSK3β, Akt, and APP genes. Rosmarinic acid and β-sitosterol showed promising effects for treating AD, according to an
