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
Rising rates of obesity and diabetes have increased demand for sugar-free products, while consumers also seek natural colorants and foods offering functional health benefits. Sorghum leaves, an underutilized part of the plant, contain health-promoting polyphenolic compounds with bioactive and coloring properties. Incorporating sorghum leaf-derived polyphenols into foods may meet both producer and consumer interest in natural colorants and value-added ingredients. This study aimed to incorporate sorghum leaf polyphenol extracts into sugar-free gelatin candies. Four formulations were produced: artificial-low color, natural-low color, artificial-high color, and natural-high color candies. Instrumental texture was evaluated using firmness and springiness measurements. Water activity was recorded using a water activity meter. Color was assessed with a colorimeter. Total phenolic content (TPC) was measured using the Folin-Ciocalteu assay. Consumers' (N = 105) acceptance of sensory properties was evaluated using 9-point hedonic scales, and purchase intent was measured before and after colorant source and sweetener informational messaging. Natural colorant formulations had significantly higher water activity than artificially colored candies. Instrumental firmness and springiness differed significantly (
