Non-traumatic cortical subarachnoid haemorrhage: diagnostic work-up and aetiological background.
Article in Neuroradiology, 2005. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 33 papers, 2 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
Only 15% of all subarachnoid haemorrhages (SAHs) are not of aneurysmal origin. Among those, circumscribed SAHs along the cortical convexity are rare and have only been described in singular case reports so far. Here, we present a collection of 12 cases of SAH along the convexity, of non-traumatic origin. Over a period of 10 years, 12 cases of circumscribed SAH along the convexity were identified at our clinic. The clinical presentations, neuroradiological SAH characteristics, further diagnostic work-up to identify the underlying aetiologies, the therapy and clinical outcome were analysed. The patients' chief complaints were unspecific cephalgia, focal or generalised seizures and focal neurological deficits. Typical signs of basal SAH, such as nuchal rigidity, thunderclap-headache or alteration of consciousness, were rare. Magnetic resonance imaging (MRI) and digital subtraction angiography (DSA) revealed different aetiologies, namely postpartal posterior encephalopathy (three), cerebral vasculitis (two), dural sinus thrombosis (two), cortical venous thrombosis (one), intracerebral abscesses (one) and cerebral cavernoma (one). Two cases remained unresolved. Treatment of the underlying disease and symptomatic medication led to good clinical outcome in almost all cases. On the basis of these findings, we demonstrate that the clinical presentation, localisation and aetiology of cortical SAH differ clearly from other SAHs. A diagnostic work-up with MRI and eventually DSA is essential. Mostly, the causative disease can be identified, and specific treatment allows a favourable outcome.
