A risk-assessment model to rate the occurrence and relevance of adventitious agents in the production of influenza vaccines.
Article in Vaccine, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
Influenza vaccine production has traditionally relied on the use of embryonated chicken eggs for virus isolation and propagation, but recently, cell-culture-derived manufacturing methods have been introduced. During influenza vaccine production, by either conventional or cell culture methods, there is a risk of incidental contamination by adventitious agents. Thus, a risk-assessment model has been developed to qualitatively assess the potential risk of vaccine process contamination by viral pathogens. The model takes into account the basic growth characteristics of each virus, its ability to grow in different cell substrates and resistance to processing steps during vaccine manufacture. The risk-assessment model has been applied to various pathogens to determine potential risk and relevance in different manufacturing scenarios, using different cell substrates for virus propagation, including Madin-Darby canine kidney (MDCK) cells. Avian viruses, introduced via use of embryonated eggs for virus isolation, were found to present the greatest risk, irrespective of the substrate used for influenza virus propagation. The use of MDCK cells to propagate vaccine virus from egg-isolated influenza virus strains does not introduce a new or greater adventitious virus risk, compared with egg-based vaccine production. Indeed, the adventitious virus risk is potentially reduced as fewer viruses are able to grow in MDCK cells.
