Absence of E protein arrests transmissible gastroenteritis coronavirus maturation in the secretory pathway.
Article in Virology, 2007. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 85 papers, 1 of them a synthesis that pooled 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.
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
A recombinant transmissible gastroenteritis coronavirus (rTGEV) in which E gene was deleted (rTGEV-DeltaE) has been engineered. This deletion mutant only grows in cells expressing E protein (E(+) cells) indicating that E was an essential gene for TGEV replication. Electron microscopy studies of rTGEV-DeltaE infected BHK-pAPN-E(-) cells showed that only immature intracellular virions were assembled. These virions were non-infectious and not secreted to the extracellular medium in BHK-pAPN-E(-) cells. RNA and protein composition analysis by RNase-gold and immunoelectron microscopy showed that rTGEV-DeltaE virions contained RNA and also all the structural TGEV proteins, except the deleted E protein. Nevertheless, full virion maturation was blocked. Studies of the rTGEV-DeltaE subcellular localization by confocal and immunoelectron microscopy in infected E(-) cells showed that in the absence of E protein virus trafficking was arrested in the intermediate compartment. Therefore, the absence of E protein in TGEV resulted in two actions, a blockade of virus trafficking in the membranes of the secretory pathway, and prevention of full virus maturation.
