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 development of infectious cDNA for different alphaviruses opened an opportunity to explore their attenuation by extensively modifying the viral genomes, an approach that might minimize or exclude the reversion to the wild-type, pathogenic phenotype. Moreover, the genomes of such alphaviruses can be engineered to contain RNA elements that would be functional only in cells of vertebrate, but not insect, origin. In the present study, we developed a recombinant VEEV that is more attenuated than TC-83 and capable of replicating only in vertebrate cells. This phenotype was achieved by rendering the translation of the viral structural proteins, and ultimately viral replication, dependent on the internal ribosome entry site of encephalomyocarditis virus (EMCV IRES). This recombinant virus was viable, but required additional, adaptive mutations in nsP2 that strongly increased its replication rates. In spite of efficient replication in cultured vertebrate cells, the genetically modified VEEV demonstrated a highly attenuated phenotype in newborn mice, and yet induced protective immunity against VEEV infection.
