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
The NS1 protein of classical swine H1N1 influenza A virus evolved dynamically during the past 80 years, most notable changes happened in the four C-terminal sequences and the C-terminal truncation of 11 amino acids. However, the role of these changes on the virulence of classical swine H1N1 influenza A virus remains unknown. Using reverse genetics, three NS1 mutant viruses (RSEV, GSEI, and EPEV) and a wild-type virus (PEQK) were generated from A/Swine/Shanghai/1/2005 virus and the pathogenicity of the viruses was determined in mice. The results showed that RSEV and PEQK viruses could not infect the mice. By contrast, GSEI and EPEV viruses could replicate in the lungs of mice without prior adaptation. The viral titers in lungs from GSEI and EPEV virus-infected mice were 2,300 and 7 pfu/g at fourth-day post-infection, respectively. Mild-to-moderate alveolitis was observed in the histopathological test of lungs from GSEI and EPEV virus-infected mice. The results indicated that C-terminal GSEI and EPEV motifs of NS1 protein involved in viral virulence and facilitated the A/Swine/Shanghai/1/2005 virus crossing the species barrier from swine to mice.
