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

Posterior fossa arteriovenous malformations (AVMs) are uncommon lesions that carry significant risk due to their proximity to the brainstem. We present the case of an 18-year-old female who suffered a sudden severe headache and was found to have a subarachnoid haemorrhage caused by a cervicomedullary junction AVM of the juvenile Type IIa subtype. Multimodality imaging with noncontrast CT, MRI and digital subtraction angiography (DSA) confirmed a posterior fossa AVM centred at the cervicomedullary junction. The patient was managed conservatively with strict blood pressure control and analgesia; Gamma Knife radiosurgery was considered but deferred given the diffuse nidus and the lesion's location adjacent to the medulla. This case illustrates the diagnostic and therapeutic challenges of posterior fossa AVMs in young patients and highlights the crucial role of multimodality imaging in guiding management decisions.
