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

Tick-borne encephalitis virus (TBEV) is the most prevalent tick-borne viral disease in Europe and Asia. There are three main subtypes of the virus: European, Siberian, and Far Eastern, each of which having distinctive ecology, clinical presentation, and geographic distribution. In recent years, other TBEV subtypes have been described, namely the Himalayan and Baikalian subtypes. Differences in virulence between TBEV subtypes have been described, with the Far Eastern subtype causing the most severe disease in humans. Considering the emergence of new TBEV foci, the genetic characterisation of the virus in endemic regions is crucial to not only better understand its epidemiology, but also to identify possible genetic determinants of virulence, as well as develop accurate diagnostics and therapeutics. In our previous study, we identified TBEV in six localities of the Kyrgyz Republic (Kyrgyzstan), and Ala-Archa National Nature Park as a focus of TBEV transmission. Whilst we were able to retrieve the first partial TBEV sequence from Kyrgyzstan from Ixodes persulcatus ticks, we were unable to retrieve a complete genome sequence at that time. In this study, we have utilised a sequence-independent single-primer amplification (SISPA) protocol and retrieved the complete genome sequence of our previous 2009 TBEV tick sample (strain KY09) producing the third complete TBEV genome from Kyrgyzstan, and the first genome from the region clustering within the Vasilchenko lineage, suggesting a wider distribution for the lineage than was previously thought. We have also developed a tiling amplicon scheme for Siberian TBEV (TBEV-Sib) which produced > 90 % reference coverage at 100x sequencing depths for samples with as little as 1.13×10
