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

Chronic hepatitis B virus (HBV) infections are associated with persistent immune killing of infected hepatocytes. Hepatocytes constitute a largely self-renewing population. Thus, immune killing may exert selective pressure on the population, leading it to evolve in order to survive. A gradual course of hepatocyte evolution toward an HBV-resistant state is suggested by the substantial decline in the fraction of infected hepatocytes that occurs during the course of chronic infections. Consistent with hepatocyte evolution, clones of >1,000 hepatocytes develop postinfection in the noncirrhotic livers of chimpanzees chronically infected with HBV and of woodchucks infected with woodchuck hepatitis virus (W. S. Mason, A. R. Jilbert, and J. Summers, Proc. Natl. Acad. Sci. U. S. A. 102:1139-1144, 2005; W. S. Mason et al., J. Virol. 83:8396-8408, 2009). The present study was carried out to determine (i) if extensive clonal expansion of hepatocytes also occurred in human HBV carriers, particularly in the noncirrhotic liver, and (ii) if clonal expansion included normal-appearing hepatocytes, not just hepatocytes that appear premalignant. Host DNA extracted from fragments of noncancerous liver, collected during surgical resection of hepatocellular carcinoma (HCC), was analyzed by inverse PCR for randomly integrated HBV DNA as a marker of expanding hepatocyte lineages. This analysis detected extensive clonal expansion of hepatocytes, as previously found in chronically infected chimpanzees and woodchucks. Tissue sections were stained with hematoxylin and eosin (H&E), and DNA was extracted from the adjacent section for inverse PCR to detect integrated HBV DNA. This analysis revealed that clonal expansion can occur among normal-appearing human hepatocytes.
