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

Respiratory syncytial virus (RSV) infection of most cultured cell lines causes cell-cell fusion and death. Cell fusion is caused by the fusion (F) glycoprotein and is clearly cytopathic, but other aspects of RSV infection may also contribute to cytopathology. To investigate this possibility, we generated an RSV replicon that lacks all three of its glycoprotein genes and so cannot cause cell-cell fusion or virus spread. This replicon includes a green fluorescent protein gene and an antibiotic resistance gene to enable detection and selection of replicon-containing cells. Adaptive mutations in the RSV replicon were not required for replicon maintenance. Cells containing the replicon could be cloned and passaged many times in the absence of antibiotic selection, with 99% or more of the cells retaining the replicon after each cell division. Transient expression of the F and G (attachment) glycoproteins supported the production of virions that could transfer the replicon into most cell lines tested. Since the RSV replicon is not toxic to these cultured cells and does not affect their rate of cell division, none of the 8 internal viral proteins, the viral RNA transcripts, or the host response to these molecules or their activities is cytopathic. However, the level of replicon genome and gene expression is controlled in some manner well below that of complete virus and, as such, might avoid cytotoxicity. RSV replicons could be useful for cytoplasmic gene expression in vitro and in vivo and for screening for compounds active against the viral polymerase.
