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

Wheatgrass (Triticum aestivum)  was cultivated to identify biochemical compounds and nutrients for use as dietary supplements as a new method of aquaponic plant utilisation. T. aestivum was irrigated with aquaculture process water from an extensive aquaculture unit (EAU) and an intensive aquaculture unit (IAU) of African catfish production (Clarias gariepinus) for nine days after transplanting (DAT), and plant growth was compared to a control using commercial fertiliser. Plants were cultivated in pots filled with the standard media "Einheitserde" (80% white peat, 20% clay) and a coconut and vermiculite substrate (50:50, C/V). The best plant growth was observed in T. aestivum irrigated with IAU and cultured in the C/V substrate, while no influence of the different irrigation solutions was found in moisture content, crude protein, crude lipid, ash, or crude fibre. The C/V substrate functioned as a nutrient reservoir (e.g. P, K, Mg, B, Fe, Mn), except for nitrogen, which originated in substantial proportions from the IAU process water. T. aestivum grown in the C/V substrate showed no difference in mineral content between EAU and IAU, while process water from the IAU only improved growth parameters. Vitamin B
