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
Introduction: Strawberries are characterized by distinctive flavors, sweet taste profiles, and abundant bioactive nutrients. However, they have a tender texture, and are prone to rapid ripening and softening post-harvest, leading to a loss of their commercial quality and marketability. Exogenous adenosine triphosphate (ATP) at appropriate concentrations can activate beneficial extracellular ATP signaling pathways that preserve agricultural product quality and extend shelf life during storage. However, research on the effects of exogenous ATP on strawberries is limited. Therefore, we aimed to analyze the regulatory effects of different concentrations of ATP on strawberry ripening by exploring its effects on sugar and organic acid metabolism in strawberries. Methods: The effects of different concentrations of ATP on the quality, sugar metabolism, and organic acids of strawberry fruits stored at 4 °C for 15 days were examined. Results: The results demonstrated that 1 mM ATP effectively maintained fruit color, promoted the accumulation of soluble solids, reduced titratable acidity, and inhibited the decline in pulp firmness in sugar metabolism. Treatment with 1 mM ATP promoted the accumulation of glucose, fructose, and sucrose in strawberries, and enhanced the activities of acid invertase (AI), neutral invertase (NI), sucrose synthase (SS-s), sucrose cleavage enzyme (SS-c), and hexokinase (HK). It upregulated the expression of Conclusion: Overall, 1 mM ATP treatment maintained strawberry fruit quality by regulating the expression of key genes and enzyme activities involved in sugar and organic acid metabolism in strawberries, thereby extending its shelf life.
