Subarachnoid haemorrhage (spontaneous aneurysmal).
Synthesis in BMJ clinical evidence, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 18 papers, 1 of them a synthesis 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
introductionSubarachnoid haemorrhage (SAH) may arise spontaneously or as a result of trauma. Spontaneous SAH accounts for about 5% of all strokes. Ruptured aneurysms are the cause of 85% of spontaneous SAH. The most characteristic clinical feature is sudden-onset severe headache. Other features include vomiting, photophobia, and focal neurological deficit or seizures, or both. As the headache may have insidious onset in some cases, or may even be absent, a high degree of suspicion is required to diagnose SAH with less typical presentations. METHODS AND OUTCOMES: We conducted a systematic review, aiming to answer the following clinical question: What are the effects of surgical treatments for people with confirmed aSAH? We searched: Medline, Embase, The Cochrane Library, and other important databases up to October 2014 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review).
resultsAt this update, searching of electronic databases retrieved 82 studies. After deduplication and removal of conference abstracts, 47 records were screened for inclusion in the overview. Appraisal of titles and abstracts led to the exclusion of 33 studies and the further review of 14 full publications. Of the 14 full articles evaluated, one systematic review, one RCT, and four further reports were added at this update. We performed a GRADE evaluation for six PICO combinations.
conclusionsIn this systematic overview, we categorised the efficacy for one comparison based on information about the effectiveness and safety of endovascular coiling versus surgical clipping.
