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
Objective: To investigate the mechanism underlying the association between gut microbiota metabolites and insomnia, focusing on the "gut microbiota-metabolite-target" axis. The Cinnamomi Cortex-Gardeniae Fructus (CC-GF) combination was used as an intervention. Methods: Network pharmacology was applied to predict insomnia-related gut microbiota metabolites and their targets. A PCPA-induced rat insomnia model was established, and gut microbiota dysbiosis was validated using 16S rRNA sequencing. Core gut microbiota were identified, and core targets were screened via protein-protein interaction (PPI) network analysis and multi-algorithm ranking. A "core microbiota-metabolite-core target" network was constructed, and binding affinities were verified using molecular docking and molecular dynamics simulations. Results: Twenty-eight targets were predicted, and CASP3, NFE2L2, HDAC1, and CCND1 were identified as core targets related to oxidative stress, apoptosis, epigenetic regulation, and circadian disturbance. In the insomnia model, the beneficial genera Conclusion: This study elucidates the "gut microbiota-metabolite-target" axis in insomnia and highlights the "
