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

introductionConstipation is reported in 52% of people with advanced malignancy. This figure rises to 87% in people who are terminally ill and taking opioids. Constipation may be the most common adverse effect of opioids. There is no reason to believe that people with chronic non-malignant disease who take opioids will be any less troubled by this adverse effect. METHODS AND OUTCOMES: We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of: oral laxatives, rectally applied medications, and opioid antagonists for constipation in people prescribed opioids? We searched: Medline, Embase, The Cochrane Library, and other important databases up to August 2009 (Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA).

resultsWe found 23 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions.

conclusionsIn this systematic review we present information relating to the effectiveness and safety of the following interventions: arachis oil enemas, bisacodyl, co-danthrusate/co-danthramer, docusate, glycerol suppositories, ispaghula husk, lactulose, liquid paraffin, macrogols plus electrolyte solutions, magnesium salts, methylcellulose, opioid antagonists, phosphate enemas, senna, sodium citrate micro-enema, and sodium picosulfate.
