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
Effects of ultrasound-assisted pretreatment combined with air impingement drying on drying kinetics, microstructure, crystallinity, color, total phenolic content (TPC), and antioxidant capacity of Chaenomeles sinensis slices were investigated in the current study. Experimental results showed that ultrasonic pretreatment significantly enhanced heat and mass transfer, reducing total drying time by 12.50% to 43.75% compared to untreated samples. Optical microscopy and scanning electron microscopy revealed that ultrasound disrupted cell walls, loosened tissue structure, and increased porosity, creating microchannels favorable for moisture diffusion. X-ray diffraction and color analysis indicated that moderate ultrasonic treatments improved crystallinity and reduced color degradation. Furthermore, increasing the ultrasonic time and power could greatly increase the TPC and FRAP values in fresh samples. The highest TPC, 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity, and ferric-ion reducing antioxidant power (FRAP) values in dried products were achieved with ultrasonic pretreatment at 160 W for 40 min, i.e., 8.71 mg/g, 6.14, and 23.18 mmol Trolox/g, respectively. These findings suggest that appropriate ultrasonic pretreatment facilitates the release and retention of bioactive compounds by altering the microstructure and crystallinity, as well as shortening drying duration. In summary, ultrasound-assisted air impingement drying is an effective approach to processing C. sinensis slices with the improvement of drying efficiency and physicochemical properties of products.
