Understanding microRNAs in the context of bacterial versus viral infections.
Article in Medicine and pharmacy reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: MicroRNAs (miRNAs), small non-coding RNAs that regulate gene expression, have emerged as biomarkers for differentiating infection types due to their distinct expression profiles in response to pathogens. This study explores miRNA profiling using microarray technology to identify miRNA signatures that differentiate viral from bacterial infections in plasma samples. Methods: Plasma samples were collected from patients diagnosed with either bacterial (e.g., pneumonia) or viral (e.g., human papillomavirus) infections; control samples were used to evaluate altered miRNA pattern, followed by Ingenuity Pathway Analysis (IPA) analysis. Results: Microarray analysis revealed distinct miRNA expression patterns for bacterial and viral infections. In bacterial infections, 11 miRNAs were significantly downregulated compared to controls. Similarly, 12 miRNAs were downregulated in viral infections. Pathway analysis indicated that the altered miRNAs in bacterial infections were linked to immune and inflammatory pathways. In contrast, viral infections were associated with miRNAs involved in cellular stress and replication processes. Conclusion: Plasma miRNA profiling offers a promising diagnostic tool to differentiate bacterial from viral infections, providing specific miRNA signatures underlying immune responses. These findings represent a foundation for developing miRNA-based diagnostics, improving the precision of infection diagnosis, and paving the way for targeted therapeutic interventions.
