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
Efficient utilization of cellulose resources is of great significance to environmental protection and to solve the crisis of global energy shortage. In the present work, a polysaccharide (CGP-TS) was successfully produced by Chaetomium globosum CGMCC 6882 from waste tobacco stalk via submerged fermentation. Chemical composition analysis showed that the carbohydrate and protein contents in CGP-TS were 92.55% ± 3.16% and 4.73% ± 1.04%, respectively. Structural characterization indicated that CGP-TS was not pectin and composed of rhamnose, arabinose, galactose, glucose and xylose in a molar ratio of 22.2166: 9.8269: 36.2455: 3.3111: 0.416, and its molecular weight was 613.235 kDa. In vitro bioactivity and potential application investigation showed that antioxidant activities of CGP-TS against DPPH, ABTS, hydroxyl and superoxide radicals were positively correlated to its concentration from 0.5 mg/mL to 2.5 mg/mL. Meanwhile, CGP-TS exhibited immunomodulatory activity via enhancing the phagocytic activity and promoting the cytokines (TNF-α, IL-1β, IL-6 and NO) release of RAW 264.7 macrophages.
