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
Purpose: The endocannabinoid system can suppress inflammatory environment by regulating inflammatory mechanisms in immune and glial cells. Astrocytes secrete soluble inflammatory mediators. Prolonged activation of astrocytes is associated with accelerated aging in the central nervous system. MicroRNAs are increasingly shown to be critical gene regulators during inflammation and gliosis. In this study, we investigated the microRNA changes affected by anandamide (AEA), a dominant endocannabinoid in normal human astrocytes, following exposure to the HIV-1 Tat (Trans-activator of transcription) protein. Methods: We performed global human microRNA profiling in Tat-activated astrocytes on exposure to AEA. To delineate the mechanism of action, we utilized the bioinformatic tools miRWalk, KEGG, and Cytoscape to assess the global microarray data for significantly impacted miRNAs and their gene targets at the mRNA level. Results: Tat-induced activation significantly upregulated 122 miRNAs ( Conclusion: Reversed expression of a selected group of miRNAs identifies antagonistic pathways that promote an anti-inflammatory environment. Pathway analysis of these 37 key miRNAs showed gene targets that regulate inflammation and senescence.
