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

Herpes simplex virus 1 (HSV-1) is a well-adapted human pathogen that can invade the peripheral nervous system and persist there as a lifelong latent infection. Despite their ubiquity, only one natural isolate of HSV-1 (strain 17) has been sequenced. Using Illumina high-throughput sequencing of viral DNA, we obtained the genome sequences of both a laboratory strain (F) and a low-passage clinical isolate (H129). These data demonstrated the extent of interstrain variation across the entire genome of HSV-1 in both coding and noncoding regions. We found many amino acid differences distributed across the proteome of the new strain F sequence and the previously known strain 17, demonstrating the spectrum of variability among wild-type HSV-1 proteins. The clinical isolate, strain H129, displays a unique anterograde spread phenotype for which the causal mutations were completely unknown. We have defined the sequence differences in H129 and propose a number of potentially causal genes, including the neurovirulence protein ICP34.5 (RL1). Further studies will be required to demonstrate which change(s) is sufficient to recapitulate the spread defect of strain H129. Unexpectedly, these data also revealed a frameshift mutation in the UL13 kinase in our strain F isolate, demonstrating how deep genome sequencing can reveal the full complement of background mutations in any given strain, particularly those passaged or plaque purified in a laboratory setting. These data increase our knowledge of sequence variation in large DNA viruses and demonstrate the potential of deep sequencing to yield insight into DNA genome evolution and the variation among different pathogen isolates.
