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

Ginger, the rhizome of Zingiber officinale, which is used as a spice globally has a long history of medicinal use that stimulates investigators to assess its potential roles as an adjuvant therapy or alternative medicine in a range of diseases. Anti-inflammatory, antioxidant, antitumor, and antiulcer effects of ginger have been proven in many scientific studies, and some of the ancient applications of ginger as a home remedy has been confirmed in human. In this review, we summarized the current evidence on the effects of ginger consumption on gastrointestinal disorders based on clinical trials. Our data indicate that divided lower daily dosage of 1500 mg ginger is beneficial for nausea relief. Because of limited number of studies on some other gastrointestinal disorders, the results may not be as much powered as to find significant results. Therefore, more extensive and well-controlled human studies of ginger or its standard extracts are required to demonstrate its efficacy as a gastroprotective agent. Dose-finding studies should be undertaken to accurately determine the effective dose and preparation of ginger in further clinical trials protocol.
