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

Paramyxoviruses, such as Newcastle disease virus (NDV), assemble in and bud from plasma membranes of infected cells. To explore the role of each of the NDV structural proteins in virion assembly and release, virus-like particles (VLPs) released from avian cells expressing all possible combinations of the nucleoprotein (NP), membrane or matrix protein (M), an uncleaved fusion protein (F-K115Q), and hemagglutinin-neuraminidase (HN) protein were characterized for densities, protein content, and efficiencies of release. Coexpression of all four proteins resulted in the release of VLPs with densities and efficiencies of release (1.18 to 1.16 g/cm(3) and 83.8% +/- 1.1%, respectively) similar to those of authentic virions. Expression of M protein alone, but not NP, F-K115Q, or HN protein individually, resulted in efficient VLP release, and expression of all different combinations of proteins in the absence of M protein did not result in particle release. Expression of any combination of proteins that included M protein yielded VLPs, although with different densities and efficiencies of release. To address the roles of NP, F, and HN proteins in VLP assembly, the interactions of proteins in VLPs formed with different combinations of viral proteins were characterized by coimmunoprecipitation. The colocalization of M protein with cell surface F and HN proteins in cells expressing all combinations of viral proteins was characterized. Taken together, the results show that M protein is necessary and sufficient for NDV budding. Furthermore, they suggest that M-HN and M-NP interactions are responsible for incorporation of HN and NP proteins into VLPs and that F protein is incorporated indirectly due to interactions with NP and HN protein.
