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
Research background: The almond beverage enriched with flaxseed is an important source of α-linolenic acid (ALA), an essential omega-3 fatty acid that the human body cannot synthesize and must obtain it through the diet. Although omega-3 fatty acids are essential for all people, this beverage is particularly beneficial for those who do not consume fish, such as vegans and vegetarians, as it is a plant-based source of ALA. Its versatility allows it to be easily incorporated into different recipes and daily meals. Therefore, this study aims to optimize a plant-based almond beverage enriched with flaxseed, offering a natural and completely vegan source of omega-3 fatty acids. Experimental approach: The initial formulation of the drink comprised 75 % raw almonds and 25 % flaxseed mixture, water (in 1:6 ratio) and 4 % sweetener. Following preliminary tests, the beverage was optimized using the mixing method to determine the ideal proportions of the ingredients. This process resulted in 16 samples, each with different minimum and maximum amounts of each ingredient, which were replicated and analyzed. One of the formulations achieved an optimal mass fraction of 4.27 mg/g of omega-3 fatty acids and a viscosity of 6.03 mPa Results and conclusions: The addition of flaxseed had a significant effect on the lipid profile and increased the alpha-linolenic acid content in the beverage by 1960 times, eventually reaching 3.92 %. This optimization enriched the beverage with omega-3 fatty acids and improved the concentration of antioxidants and carotenoids. Importantly, these improvements did not significantly affect the color and viscosity of the final product, creating an affordable option that can benefit the vegan and vegetarian community. Novelty and scientific contribution: This study shows that the response surface model effectively identified the ideal composition for the beverage, leading to an optimized formulation of a plant-based drink. This composition could have promising applications in the food industry.
