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
Background: The interaction between HIV-1 and host immune cells, particularly macrophages, is crucial in understanding viral persistence and pathogenesis. This study aims to explore the impact of HIV-1 infection on macrophage microRNA (miRNA) expression profiles using a systems biology approach to uncover the potential role of miRNAs in modulating macrophage functionality and identify key miRNA targets that may serve as therapeutic avenues. Methods: PMA-differentiated THP-1 cells were used to model macrophage infection with HIV-1. A custom miRNA microarray was performed to identify dysregulated miRNAs following infection. miRTarBase was utilized for miRNA target identification, revealing gene targets associated with the dysregulated miRNAs. A protein-protein interaction (PPI) map of miRNA targets and their first interactors was constructed, with key nodes identified based on a calculated disease score, which considered degree, betweenness centrality, average shortest path length, and clustering coefficient. Gene Ontology molecular function analysis was also conducted on the identified targets. Results: The miRNA microarray identified 23 dysregulated miRNAs in HIV-1-infected macrophages, with 8 upregulated and 15 downregulated. Among these, the top 10 dysregulated miRNAs targeted over 2000 unique genes. PPI analysis revealed key nodes in the upregulated miRNA network, including Conclusions: HIV-1 infection induces significant dysregulation of miRNAs in macrophages, impacting a wide array of gene targets and molecular functions. These findings suggest that miRNA-mediated regulation may play a crucial role in HIV-1 pathogenesis within macrophages and present potential targets for miRNA-based therapeutic strategies.
