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

backgroundHepatitis C virus (HCV) is one of the major causes of cirrhosis and hepatocellular carcinoma with an estimation of 185 million people with infection. The E2 is the main target for neutralizing antibody responses and the variation of this region is related to maintenance of persistent infection by emerging escape variants and subsequent development of chronic infection. While both E1 and E2 are hypervariable in nature, it is difficult to design vaccines or therapeutic drugs against them.

objectivesThe objective of this study was to characterize genotype 5a E1 and E2 sequences to determine possible glycosylation sites, conserved B-cell epitopes and peptides in HCV that could be useful targets in design of vaccine and entry inhibitors. PATIENTS AND

methodsThis study was conducted through PCR amplification of E1 and E2 regions, sequencing, prediction of B-cell epitopes, analysis of N-linked glycosylation and peptide design in 18 samples of HCV genotype 5a from South African.

resultsDifferences in the probability of glycosylation in E1 and E2 regions were observed in this study. Three conserved antigenic B-cell epitopes were predicted in the E2 regions and also 11 short peptides were designed from the highly conserved residues.

conclusionsThis study provided conserved B-cell epitopes and peptides that can be useful for designing entry inhibitors and vaccines able to cover a global population, especially where genotype 5a is common.
