Synthesis in BMJ clinical evidence, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 3 of them syntheses that pooled 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.
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
introductionInvoluntary, localised leg cramps are common and typically affect the calf muscles at night. METHODS AND OUTCOMES: We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of treatments for idiopathic leg cramps? What are the effects of treatments for leg cramps in pregnancy? We searched: Medline, Embase, The Cochrane Library, and other important databases up to September 2008 (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 12 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: analgesics, anti-epileptic drugs, calcium salts, compression hosiery, magnesium salts, multivitamin and mineral supplements, quinine alone or with theophylline, sodium chloride, and stretching exercises.
