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

Regardless of recent advances in the development of anti-retroviral drugs, it is still extremely difficult to eradicate HIV-1 from infected individuals. The characterization of the HIV-1 provirus, a type of viral reservoir, with a high resolution is key to HIV-1 cure research. Here, we demonstrate that DNA-capture-seq is a powerful tool to obtain comprehensive information on the HIV-1 provirus. We use biotinylated DNA probes targeting the entire HIV-1 sequence to capture fragments containing HIV-1 sequences from DNA-seq libraries prepared for high throughput sequencing. We demonstrate that the protocol provided the entire proviral sequence from the beginning of the 5' LTR to the end of the 3' LTR. Since HIV-1 DNA-probes can hybridize not only viral fragments but also virus-host chimeric ones, the viral integration site information can also be obtained. We verify the efficiency of the protocol by using latently infected cell lines, such as ACH-2 and J1.1, and newly generated ones. The results reveal that the 2 new clones that we analyse harbour one copy of replication-competent provirus, suggesting that latency is not caused by genetic mutations or deletions of the provirus. In conclusion, HIV-1 DNA-capture-seq is a powerful tool to characterize the HIV-1 provirus at a single nucleotide resolution and therefore might be useful for various experiments aiming for an HIV-1 cure.
