Genetic dynamic analysis of the influenza A H5N1 NS1 gene in China.
Article in PloS one, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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 direct precursors of the A/Goose/Guangdong/1/1996 (GS/GD) virus lineage and its reassortants have been established geographically and ecologically. To investigate the variation and evolutionary dynamics of H5N1 viruses, whole-genome viral sequences (n = 164) were retrieved from the NCBI Influenza Virus Resource. Here, we present phylogenetic evidence for intrasubtype reassortments among H5N1 viruses isolated from China during 1996-2012. On the basis of phylogenetic analysis, we identified four major groups and further classified the reassortant viruses into three subgroups. Putative mosaic structures were mostly found in the viral ribonucleoprotein (vRNP) complexes and 91.0% (10/11) mosaics were obtained from terrestrial birds. Sequence variability and selection pressure analyses revealed that both surface glycoproteins (HA and NA) and nonstructural protein 1 (NS1) have higher dN/dS ratio and variability than other internal proteins. Furthermore, we detected 47 positively selected sites in genomic segments with the exception of PB2 and M1 genes. Hemagglutinin (HA) and neuraminidase (NA) are considered highly variable due to host immune pressure, however, it is not known what drives NS1 variability. Therefore, we performed a thorough analysis of the genetic variation and selective pressure of NS1 protein (462 available NS1 sequences). We found that most of positively selected sites and variable amino acids were located in the C-terminal effector domain (ED) of NS1. In addition, we focused on the NS1-RNA and NS1-protein interactions that were involved in viral replication mechanisms and host immune response. Transcriptomic analysis of H5N1-infected monkey lungs showed that certain PI3K-related genes were up-regulated.
