Incidence and possible causes of nontraumatic convexal subarachnoid haemorrhage in Chinese patients: A retrospective review.
Article in The Journal of international medical research, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
Objective To explore the incidence and possible underlying pathogenic mechanisms of nontraumatic convexal subarachnoid haemorrhage (cSAH; a rarely reported condition) in a cohort of Chinese patients. Methods Medical records from all patients with subarachnoid haemorrhage (SAH) who had been treated at Peking University Third Hospital, China, between January 2010 and December 2014 were retrospectively reviewed to identify cases of cSAH. Results Of 144 patients with SAH, cSAH was observed in 14 cases (9.7%). The most frequent presenting symptoms in cSAH cases were severe headache ( n = 8) and a focal neurological deficit ( n = 8). The parietal (10/14 patients, 71.4%) and frontal (9/14 patients, 64.3%) lobes were the most common haemorrhage sites. Cause of cSAH was identified in 11 patients: in seven cases (50.0%), significant stenosis or occlusion in the internal carotid artery system, ipsilateral to cSAH, was reported; in four cases, cSAH was caused by cerebral venous sinus thrombosis, cerebrovascular malformation, anticoagulant therapy or possible cerebral amyloid angiopathy. Conclusion cSAH is an important subtype of nonaneurysmal SAH, with diverse aetiologies. In the present study, internal carotid artery system atherosclerotic stenosis was the most frequent cause of cSAH.
