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

Protein from duckweed (Araceae, subfamily Lemnoideae) grown on diluted animal slurries for nutrient upcycling could potentially replace plant-derived feed proteins which would be more efficiently used as human food. However, little information is available on greenhouse gas (GHG) emissions from slurry-grown duckweed, and previous studies have not reported methane emissions from a similar system. Here, we report on GHG (methane, carbon dioxide and nitrous oxide) and ammonia emissions from duckweed grown on diluted cattle slurry measured in daylight and darkness, compared with emissions from diluted slurry without duckweed. We observed (i) initially high but rapidly declining methane emissions, independent of lighting or treatment, (ii) a net carbon dioxide fixation by duckweed, independent of lighting, (iii) high nitrous oxide emissions, independent of lighting, and (iv) a > 80% reduction of ammonia emissions by duckweed, independent of lighting. Our data shows potential of duckweed protein as a sustainable protein with 3.54 to 6.54 CO
