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

Influenza virus has a set of ribonucleoproteins (RNPs) consisting of viral RNAs, influenza virus polymerase subunits, and nucleoprotein. Intracellular reconstitution of the whole set of RNPs via plasmid transfection results in the generation of influenza virus. By the use of reverse genetics and dual promoters, we constructed a 23.6-kb eight-unit plasmid that contains all the required constituents to generate influenza virus in chicken cells. Our "one-plasmid" system generated higher titers of influenza virus in chicken cells than the "eight-plasmid" system, enabling a simpler approach for generating vaccine seeds. Our study identified plasmid size as a potential limiting factor affecting transfection efficiency and hence the influenza viral yield from chicken cells.
