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

Porcine parvovirus (PPV) is one of the major causes of reproductive pig disease. Due to its serious nature, wide spread and consequent great damage to the swine industry, an effective, rapid and convenient method for its detection is needed. A loop-mediated isothermal amplification (LAMP) assay was established to detect PPV infection. Two pairs of primers were specifically designed to recognize the six different sequences of open reading frame1 (ORF1) gene. The optimized LAMP program was as follows: 50 min at 59 °C followed by 3 min at 80 °C.The amplified products were analyzed both by visual inspection after staining with SYBR Green I dye and by conventional agarose gel electrophoresis. Both methods showed the same sensitivity. The limit of detection (LOD) for PPV by LAMP was 10 copies, which is 100-fold lower than conventional PCR. Our LAMP assay did not cross-react with other viruses. We used the established LAMP system to test 1100 field samples and detected 660 positives. The LAMP detection method for PPV represents a visual, sensitive and rapid assay which can detect the virus in the field, offering an attractive alternative for the PPV detection methods currently in use.
