Novel approach for quantification of hepatitis C virus in liver cirrhosis using real-time reverse transcriptase PCR.
Article in Journal of gastrointestinal surgery : official journal of the Society for Surgery of the Alimentary Tract, 2012. 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
backgroundHepatitis C virus (HCV) infects nearly 3% of the population worldwide and is a major cause of acute and chronic infections leading to fibrosis, cirrhosis, and hepatocellular carcinoma. Current laboratory diagnosis of HCV is based on specific antibody detection (anti-hepatitis C virus (anti-HCV)) in serum. As HCV replicates in the liver cells, detection and localization of HCV RNA in liver tissue are vital for diagnosis.
methodsTen biopsy samples diagnosed for cryptogenic liver cirrhosis, negative for the presence of anti-HCV and serum HCV RNA, were studied for analyzing presence of viral nucleic acid in liver tissues. Qualitative screening for HCV was done through ELISA while the nucleic acid analysis was performed through COBAS Amplicor. Detection of HCV RNA in liver tissue biopsies was performed following standard protocol of HCV detection kit (Shenzhen PG Biotech) with modifications using Light Cycler 2.0 (minimum detection limit 10 copies/ml).
resultQuantitative detection in liver biopsies following the modified method showed the presence of HCV RNA in three samples out of the ten studied.
conclusionThe results indicate that using Light Cycler 2.0, following the modified technique described, constitutes a reliable method of quantitative detection and localization of HCV in tissue in "serosilent" HCV infection.
