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

Chronic constipation is an important component of clinical gastroenterology practice worldwide. Based on the definition, either self-reported or using Rome criteria, chronic constipation can affect from 2% to 27% of the population. Constipation is physically and mentally troublesome for many patients, and can significantly interfere with their daily living and well-being. Although only a proportion of patients with constipation seek medical care, most of them use prescribed or over-the-counter medication to improve their condition. The health care costs of constipation are significant as evidenced by the hundreds of million dollars spent yearly on laxatives alone. Because constipation is more common in older patients and life expectancy is increasing, an increase in the prevalence of constipation is expected in the years to come, with the associated impact on quality of life and socioeconomic burden.
