Safety and efficacy of a feed additive consisting of a dry grape extract (Nor-Grape® α) for all avian species (Nor-Feed S.A.S.).

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
Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of a feed additive consisting of a dry grape extract (Nor-Grape® α) as a zootechnical feed additive, functional group physiological condition stabilisers - increase antioxidant defences, for all avian species. The additive is already authorised for use as a feed flavouring for all animal species, except dogs. The FEEDAP Panel concluded that the additive is safe for all avian species. The use of the additive in animal nutrition is of no concern for consumer safety. Based on the data submitted, the FEEDAP Panel could not conclude on the potential of the additive to be a skin or eye irritant or a dermal or respiratory sensitiser. However, the Panel considered that exposure through inhalation is likely. The use of the feed additive is considered safe for the environment. The Panel was unable to conclude on the potential of the additive to be efficacious under the proposed conditions of use.
