1 · What the graph read from it

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.

2 · The registry

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

Five matching sets of nonmalignant liver tissues and hepatocellular carcinoma (HCC) samples from individuals chronically infected with hepatitis B virus (HBV) were examined. The HBV genomic sequences were determined by using overlapping PCR amplicons covering the entire viral genome. Four pairs of tissues were infected with HBV genotype C, while one pair was infected with HBV genotype B. HBV replication markers were found in all tissues. In the majority of HCC samples, the levels of pregenomic/precore RNA (pgRNA) and covalently closed circular DNA (cccDNA) were lower than those in liver tissue counterparts. Regardless of the presence of HBV replication markers, (i) integrant-derived HBV RNAs (id-RNAs) were found in all tissues by reverse transcription-PCR (RT-PCR) analysis and were considerably abundant or predominant in 6/10 tissue samples (2 liver and 4 HCC samples), (ii) RNAs that were polyadenylated using the cryptic HBV polyadenylation signal and therefore could be produced by HBV replication or derived from integrated HBV DNA were found in 5/10 samples (3 liver and 2 HCC samples) and were considerably abundant species in 3/10 tissues (2 livers and 1 HCC), and (iii) cccDNA-transcribed RNAs polyadenylated near position 1931 were not abundant in 7/10 tissues (2 liver and 5 HCC samples) and were predominant in only two liver samples. Subsequent RNA sequencing analysis of selected liver/HCC samples also showed relative abundance of id-RNAs in most of the examined tissues. Our findings suggesting that id-RNAs could represent a significant source of HBV envelope proteins, which is independent of viral replication, are discussed in the context of the possible contribution of id-RNAs to the HBV life cycle.
