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

Background Since its initial detection in April 2009, the A/H1N1pdm influenza virus has spread rapidly in humans, with over 5,700 human deaths. However, little is known about the evolutionary dynamics of H1N1pdm and its geographic and temporal diversification.Methods Phylogenetic analysis was conducted upon the concatenated coding regions of whole-genome sequences from 290 H1N1pdm isolates sampled globally between April 1 - July 9, 2009, including relatively large samples from the US states of Wisconsin and New York. Results At least 7 phylogenetically distinct viral clades have disseminated globally and co-circulated in localities that experienced multiple introductions of H1N1pdm. The epidemics in New York and Wisconsin were dominated by two different clades, both phylogenetically distinct from the viruses first identified in California and Mexico, suggesting an important role for founder effects in determining local viral population structures. Conclusions Determining the global diversity of H1N1pdm is central to understanding the evolution and spatial spread of the current pandemic, and to predict its future impact on human populations. Our results indicate that H1N1pdm has already diversified into distinct viral lineages with defined spatial patterns.
