Detection and Analysis of West Nile Virus Structural Protein Genes in Animal or Bird Samples.

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
West Nile virus (WNV) is an important zoonotic pathogen, which is detected mainly by identification of its RNA using PCR. Genetic differentiation between WNV lineages is usually performed by complete genome sequencing, which is not available in many research and diagnostic laboratories. In this chapter, we describe a protocol for detection and analysis of WNV samples by sequencing the entire region of their structural genes capsid (C), preM/membrane, and envelope. The primary step is the detection of WNV RNA by quantitative PCR of the NS2A gene or the C gene regions. Next, the entire region containing the structural protein genes is amplified by PCR. The primary PCR product is then amplified again in parallel reactions, and these secondary PCR products are sequenced. Finally, bioinformatic analysis enables detection of mutations and classification of the samples of interest. This protocol is designed to be used by any laboratory equipped for endpoint and quantitative PCR. The sequencing can be performed either in-house or outsourced to a third-party service provider. This protocol may therefore be useful for rapid and affordable classification of WNV samples, obviating the need for complete genome sequencing.
