Ammonium sulphate precipitation of recombinant adenovirus from culture medium: an easy method to increase the total virus yield.
Article in Gene therapy, 2000. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers.
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
In the majority of the methods for purifying and concentrating recombinant adenoviruses (rAds) the virus that is associated with the helper cells is harvested, while the virus that is present in the cell-culture medium is discarded. During routine propagation of adenovirus type-5 vectors at optimised conditions we noted that, on average, 47% of the total amount of virus is present in the culture medium. To recover and concentrate these rAds from the medium, we devised a method, which is based on ammonium sulphate ((NH4)2SO4) precipitation. At 40% (NH4)2SO4 saturation, 95 +/- 6% of the available virus precipitates from the medium, while the majority of the protein (85%) remains in solution. In contrast to adenovirus precipitation with polyethylene glycol, the (NH4)2SO4 precipitation technique allows collection of precipitated rAds by filtration. We demonstrate here that (NH4)2SO4 precipitation of rAds from cell-culture medium is a simple and fast technique that can be used in combination with standard virus isolation methods to increase the yields of rAds.
