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

objectiveReversible cerebral vasoconstriction syndrome (RCVS) is an underestimated cause of thunderclap headache that shares many characteristics with subarachnoid hemorrhage (SAH). This fact makes the two easily confused by emergency physicians. This study evaluated the clinical manifestations, radiological features, and outcomes of patients with RCVS.

methodsThe electronic medical records of 18 patients meeting the diagnostic criteria of RCVS at our emergency department between January 2013 and December 2014 were retrospectively reviewed.

resultsThe mean patient age was 50.7 years, and 80% were women. Patients with RCVS encountered physicians 4.7 times before receiving an accurate diagnosis. The mean duration of symptoms until diagnosis was 9.3 days. All but one patient experienced severe headache of 8 to 10 on a numerical rating scale. A total of 44% of patients had nausea, and 66% of patients experienced worsening of the headache while gagging, leaning forward, defecating, urinating, or having sexual intercourse. The most frequently affected vessels were the middle cerebral arteries, which demonstrated a characteristic diffuse "string of beads" appearance. Four cases were complicated by SAH.

conclusionPatients with RCVS have a unique set of clinical and imaging features. Emergency physicians should have a high index of suspicion for this clinical entity to improve its rate of detection in patients with thunderclap headache when there is no evidence of aneurysmal SAH.
