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 aimed to obtain high-quality jujube powder by reducing its hygroscopicity and tendency to agglomerate. Jujube slices were pretreated with enzyme treatment (EZ), ultrasound-assisted enzyme treatment (US-EZ), cold plasma-assisted enzyme treatment (CP-EZ), and a combined cold plasma synergistic ultrasound-assisted enzyme treatment (CP-US-EZ) prior to vacuum microwave drying (MVD). Given that glucose and fructose are key contributors to hygroscopicity and caking, the impact of each pretreatment on the desugarization effect, nutritional quality, and physical properties of the resulting powder was evaluated. All four pretreatments effectively reduced sugar levels and decreased the agglomeration phenomenon, with CP-US-EZ showing the most pronounced effect. Structural analysis via scanning electron microscopy (SEM) and X-ray diffraction revealed that CP and US modified the powder microstructure, promoting the formation of microporous, spongy textures that facilitated sugar removal and slowed down the hygroscopicity. CP-US-EZ-treated powder exhibited the lowest hygroscopicity and highest contact angle, indicating enhanced resistance to moisture uptake and hydrophobicity. This group showed the greatest content of total phenolics, flavonoids, vitamin C, antioxidant capacity, and monophenols, including 3,4-dihydroxybenzoic acid, protocatechualdehyde, and rutin. These findings demonstrate that CP-US-EZ is a promising non-thermal pretreatment technology to solve the hygroscopicity problem of the powder and produce high-quality, low-sugar jujube powder.
