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
Background: Health-promoting foods that support healthy aging are attracting growing interest, and Medjool dates, energy-dense and rich in bioactives, remain underutilized in protein-based functional snacks. Objectives: The current study aims to develop and assess high-protein energy bars made with Medjool date paste, focusing on their nutritional, phytochemical, stability, and physicochemical properties. Methods: Three Medjool date-based protein bars (F1-F3) were formulated with increasing Medjool paste (45-55%) and decreasing oats (10-0%), alongside constant milk protein concentrate-whey protein isolate (20%) and complementary mix (25%), and were characterized for composition, phytochemicals and antioxidant activity, protein-polyphenol interactions (docking), microstructure, thermal behavior, color, texture, and sensory attributes. Results: Proximate composition analysis demonstrated a high nutritional profile of the fortified date bars. Moisture ranged from 11.81-13.64%, protein 22.98-24.38%, and available carbohydrates 53.27-57.01%. Fat content was 11.20-12.25%, with dietary fiber at 5.84-6.91% and ash at 2.96-3.18%. Total, reducing, and non-reducing sugars were 33.22-41.18%, 31.06-38.86%, and 2.05-2.20%. The resulting energy value of the nutritional date bars remained consistent across formulations (420.76-422.30 kcal per 100 g), indicating overall nutrient density. The antioxidant evaluation revealed total phenolic contents ranging from 562.48 to 619.26 mg GAE per 100 g, and total flavonoid concentrations from 383.42 to 395.43 mg QE per 100 g, indicating stable radical-scavenging performance across all treatments. Molecular docking revealed that epicatechin binds specifically to Conclusion: The formulated Medjool energy bars were successfully developed, showing a strong nutritional profile, high consumer acceptance, and promise as scalable, stable, nutrient-dense products for athletes and health-conscious consumers.
