Detection of hepatitis a virus from oyster by nested PCR using efficient extraction and concentration method.
Article in Journal of microbiology (Seoul, Korea), 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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 molecular methods using polymerase chain reaction have been proposed as useful tools for the identification of viral pathogens in food and water. However, the PCR-based methods are highly dependent on the methods of virus concentration and nucleic acid purification due to the low sensitivity of PCR in the presence of PCR inhibitors. We developed TPTT [tris elution buffer-PEG-TRIzol-poly(dT) magnetic bead] protocol in order to detect hepatitis A virus (HAV) inoculated in oyster digestive glands. The detection limit of HAV precipitated with zirconium hydroxide was 10(5) fold less sensitive in a nested PCR than that precipitated the HAV supernatant twice with PEG/NaCl (16% polyethylene glycol 6,000, 0.525 M NaCl) in a 1:2 (v/v) ratio, which provided an efficient detection of 0.0148 PFU/g from approximately 0.05 g of oyster homogenate. This method is efficient for potential use in the detection of HAV from shellfish and is more sensitive than most currently published tests.
