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

Seneca Valley virus 1 (SVV-1) has been associated with vesicular disease in swine, with clinical signs indistinguishable from those of other notifiable vesicular diseases such as foot-and-mouth disease. Rapid and accurate detection of SVV-1 is central to confirm the disease causing agent, and to initiate the implementation of control processes. The development of rapid, cost-effective diagnostic assays that can be used at the point of sample collection has been identified as a gap in preparedness for the control of SVV-1. This study describes the development and bench validation of two reverse transcription loop-mediated amplification (RT-LAMP) assays targeting the 5'-untranslated region (5'-UTR) and the VP3-1 region for the detection of SVV-1 that may be performed at the point of sample collection. Both assays were able to demonstrate amplification of all neat samples diluted 1/100 in negative pig epithelium tissue suspension within 8 min, when RNA was extracted prior to the RT-LAMP assay, and no amplification was observed for the other viruses tested. Simple sample preparation methods using lyophilized reagents were investigated, to negate the requirement for RNA extraction. Only a small delay in the time to amplification was observed for these lyophilized reagents, with a time from sample receipt to amplification achieved within 12 min. Although diagnostic validation is recommended, these RT-LAMP assays are highly sensitive and specific, with the potential to be a useful tool in the rapid diagnosis of SVV-1 in the field.
