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
This study investigated the synergistic effect of ultrasound in combination with pH-shifting and heating modification on the physicochemical properties, structural characteristics, and emulsifying performance of safflower seed meal globulins (SMG). Furthermore, the efficacy of the modified protein (UHA-SMG) as a natural emulsifier was evaluated for preparing lycopene (LYC)-loaded high internal phase emulsions (HIPEs). Under the suitable modification conditions (ultrasonic power: 500 W, ultrasonic time: 5 min, temperature: 70 °C, pH: 9.0), UHA-SMG exhibited improved physicochemical properties, including altered micromorphology, reduced particle size and interfacial tension, as well as enhanced zeta-potential, surface hydrophobicity, wettability, and solubility. Structural characterization via far-UV circular dichroism, UV-Vis spectroscopy, and fluorescence spectroscopy indicated that the modification altered the secondary and tertiary structures of SMG, as evidenced by a rise in α-helical content and the redistribution of internal hydrophobic groups and aromatic amino acids. At a concentration of 2.0% (w/v), UHA-SMG successfully stabilized oil-in-water HIPEs with an internal phase volume of 75%. These HIPEs demonstrated typical shear-thinning behavior, gel-like rheological characteristics (G' > G''), and excellent stability against centrifugation, heating, and long-term storage. For LYC encapsulation, the HIPEs formulated with 2.0% (w/v) UHA-SMG achieved a high encapsulation efficiency of 96.39 ± 1.34% and provided markedly enhanced stability of LYC against UV irradiation, thermal degradation, and storage compared to free LYC. In summary, the synergistic triple-modification strategy (ultrasound, heating, and pH-shifting) significantly enhanced the functionality of SMG, rendering it a promising candidate as a bio-based stabilizer for HIPEs with considerable potential in lipophilic bioactive ingredient delivery systems.
