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
Space-induced mutation is a novel approach in tea plant breeding, but its effect on processing-induced aroma formation remains unclear. This study analyzed the dynamic changes in VOCs during the processing of space-induced mutants of Dahongpao tea. The results showed that processing significantly reshaped the VOC profile, with the fermentation stage exerting the greatest impact and terpenoids serving as the major contributors. Seven characteristic VOCs (α-phellandrene, β-phellandrene, d-sylvestrene, iso-geraniol, seudenone, hexyl benzene, and nerol) were identified and a transformation network linking floral, green, woody, almond, and fruity attributes was constructed. Molecular docking revealed that VOCs exhibiting green, woody and almond characteristics could form strong binding interactions with more than 100 olfactory receptors, whereas those with floral and fruity characteristics bound to fewer receptors. This finding indicates that during the processing, the first three odor characteristics may be perceived more prominently. Overall, this study provided a theoretical basis for the aroma evaluation of space-induced mutant tea.
