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
Longan is widely consumed due to its high nutritional value. The growing area has substantial effect on nutrient component and secondary metabolism of fruits. The aim of this study was to analyze the differences in physicochemical characteristics, polyphenol profiles, and antioxidant activity of longan fruits grown in four regions of China. Two representative cultivars 'Shixia' and 'Chuliang' located in Chongqing, Guanxi, Zhanjiang and Hainan were collected and analyzed. The results showed that the fruit weights, edible rates, and total soluble solids were 5.63-12.57 g, 52.7-68.7% and 17.54-23.68%, respectively. The titratable acids, reducing sugars, vitamin C contents were 0.22-0.62%, 2.27-5.55% and 68.29-157.34 mg/100 g, respectively. Interestingly, contents of total polyphenols and antioxidant activities in longan pericarps from Chongqing were higher than those from low-latitude regions for two cultivars. In addition, 10 polyphenols were detected by UPLC-QqQ-MS/MS which showed that the content of polyphenols was much higher in longan pericarps than in pulps. The content of polyphenol profiles in longan was mainly influenced by its tissue distribution. Cultivar type may also affect the polyphenol profile of longan.
