A Randomized Controlled Trial on the Safety and Cognitive Benefits of a Novel Functional Drink from a Purple Waxy Corn Byproduct in Peri- and Postmenopausal Women.

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
Fulfilling the demand for functional food with cost safety and environmental sustainability, our novel anthocyanin-enriched functional drink containing the purple waxy corn cob-derived functional ingredient "MP1" showed cognitive enhancing effects with safety in bilaterally ovariectomized rats, a validated model of menopause. Since no clinical evidence that confirms the mentioned effect was available until now, we conducted a two-arm, randomized, double-blind, placebo-controlled, crossover study to confirm the benefits mentioned above. A total of 32 menopausal participants were divided into placebo and MP1 (400 mg) groups, and were subject to a 2-month study period. Safety parameters, working memory and brain components, especially N100 and P300, the negative and positive potentials derived from the event-related potential (ERP) which indicated attention and cognitive processing, together with oxidative stress markers acetylcholinesterase (AChE) and monoamine oxidase (MAO), were assessed at baseline and every month. No serious side effects or toxicity signs were observed. Subjects who consumed MP1 also had decreased N100 and P300 latency, improved working memory and decreased oxidative stress status. Therefore, a byproduct of purple corn can successfully serve as a novel functional ingredient for developing a cognitive enhancer drink with the qualities of safety, cost reduction, and environmental sustainability promotion.
