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

The RNA genome of the hepatitis C virus (HCV) diversifies rapidly during the acute phase of infection, but the selective forces that drive this process remain poorly defined. Here we examined whether Darwinian selection pressure imposed by CD8(+) T cells is a dominant force driving early amino acid replacement in HCV viral populations. This question was addressed in two chimpanzees followed for 8 to 10 years after infection with a well-defined inoculum composed of a clonal genotype 1a (isolate H77C) HCV genome. Detailed characterization of CD8(+) T cell responses combined with sequencing of recovered virus at frequent intervals revealed that most acute-phase nonsynonymous mutations were clustered in class I epitopes and appeared much earlier than those in the remainder of the HCV genome. Moreover, the ratio of nonsynonymous to synonymous mutations, a measure of positive selection pressure, was increased 50-fold in class I epitopes compared with the rest of the HCV genome. Finally, some mutation of the clonal H77C genome toward a genotype 1a consensus sequence considered most fit for replication was observed during the acute phase of infection, but the majority of these amino acid substitutions occurred slowly over several years of chronic infection. Together these observations indicate that during acute hepatitis C, virus evolution was driven primarily by positive selection pressure exerted by CD8(+) T cells. This influence of immune pressure on viral evolution appears to subside as chronic infection is established and genetic drift becomes the dominant evolutionary force.
