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

Recently, there has been a renewed and rapidly growing interest globally in the cultivation of the non-psychoactive variety of Cannabis more commonly referred to as hemp. However, there remains a scarcity of available scientific information on the water use of hemp to optimally guide its large-scale production. To address this knowledge gap, eligible peer-reviewed publications acquired from the Scopus, Web of Science and Google Scholar abstract and citation databases, were analysed using Biblioshiny and VOSviewer to gain further insights on the water use of this crop. A key finding emanating from this scoping review and bibliometric analysis was that the water use of hemp ranged from approximately 220-700 mm throughout the growing season, with daily water use generally ranging between ~ 4.00 mm d
