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
Two pretreatments (ultrasound sonication [US] and microwave [MW]) and drying techniques (hot air [HA] and freeze-drying [FD]) were used to assess the in vitro bioaccessibility of phenols, carotenoids, and antioxidant activity in three tomato cultivars (Zzx171, Zzx162, and Zzx65). The metabolome-chemometric analysis showed that tomato cultivars dried by FD and HA differed in metabolites. HA samples contained methoxytyrosine and aconitane-type diterpenoids. US-HA enhanced total phenol content bioaccessibility by 64.72%-74.25% in three tomato cultivars after digestion (intestinal phase). US-HA increased the protocatechuic acid levels in all three tomato cultivars in the intestinal phase, but by 55.23% in Zzx65 compared to the undigested samples. Despite all adopted postharvest pretreatments and drying, US-HA retained chlorogenic acid, 4-O-caffeinyliquinic acid, and rutin better, due to microstructure changes in the intestinal phase, and Zzx65 treated with US-HA retained the most. In undigested samples, US-FD improved total carotenoids, lycopene, and β-carotene retention, but the inaccessibility was reduced significantly during in vitro digestion. Cultivar × postharvest treatment affected all phenolic compounds, carotenoids, and antioxidant activities in the intestinal phase. US-HA had improved antioxidant power (FRAP) and 3-ethylbenzothiazoline-6-sulfonic acid (ABTS) scavenging activity in the intestinal phase. PRACTICAL APPLICATION: Tomatoes are an important part of the human diet. Their high perishability reduces their nutritional and microbiological quality. The lack of cold storage infrastructure in developing countries contributes to food waste. Convective hot air drying is suitable for recycling fresh market waste products as supplement powders. The ultrasound pretreatment protects bioactive compounds in tomato fruit and is non-thermal. There are several limitations, including equipment cost, energy efficiency, and integration with commercial systems, which limit ultrasound-assisted drying's scalability. The integration of US-HA treatment (ultrasound-assisted hot air drying) could reduce food waste and contribute to the sustainable development goals in agricultural industries.
