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

The net environmental implications of shifting aquaculture feed provisioning from wild-caught fishmeal to crop-based ingredients remain understudied, with little attention paid to multiple environmental pressures or the importance of where ingredients are sourced from. Here we model the change in environmental footprint (a cumulative and spatial measure of greenhouse gas emissions, habitat disturbance, excess nutrient and water consumption pressures) of shifting dependence from largely fish-based to plant-based ingredients in feeds for Atlantic salmon farming. We show that average differences exist between feeds in their cumulative and individual environmental pressures, but more importantly, the locations where feed raw materials are produced and processed drives far more variability in footprint within a feed than the typical variation between feeds. We demonstrate that responsible sourcing will be critical for sustainable feed production across all farming systems as the next generation of ingredients is developed.
