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

Hepatitis A virus (HAV) is a wide spread pathogenic agent and is the common cause of acute Hepatitis A worldwide. Passive immunization of HAV plays an extremely important role in post-exposure prophylaxis with clinical applications often requiring large amounts of antibody. As an alternative to the in vitro production of recombinant proteins, expression of monoclonal antibodies (mAbs) in the milk of transgenic animals is currently used being associated with low production costs and high activity. In this paper, eight founder lines of transgenic mice were generated by co-microinjection of the two cassettes encoding the heavy- and light-chains of a neutralizing anti-HAV antibody, respectively. The expressed heavy- and light-chains of the mAb were correctly assembled and modified in the mammary gland as detected by western blotting. High expression levels of the antibody were achieved during the lactation period and found to be independent of the copy numbers of integrated transgenes. The highest level was up to 32.2 mg/ml. The binding specificity and neutralizing activity of the expressed mAb were assayed by ELISA and neutralizing test, showing that it is capable to neutralize the JN strain of Hepatitis A virus efficiently. Therefore, our results suggest that a large-scale and efficient production of the anti-HAV mAb in the milk of transgenic farm animals would be feasible in the future.
