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

backgroundAlice in Wonderland syndrome (AIWS) is a rare sensory perception disorder, most often caused by migraine in adults. We aimed to characterize the clinical characteristics of AIWS in a cohort of vestibular migraine (VM) patients.

methodsRetrospective chart review of patients diagnosed with VM seen between August 2014 and January 2018.

resultsSeventeen patients were identified (10 women) with a median age at onset of 45 years (range 15-61 years), and median age at presentation of 49 years (range 17-63 years). Eighty-two percent reported 1 AIWS symptom, 12% reported 3 symptoms, and 6% described 2 symptoms. The most common symptom was visual distortions (47%), followed by extrapersonal misperceptions (41%) and somesthetic distortions (29%). Most AIWS occurred during VM episodes (77%). Eleven patients were seen in follow-up; 10 described complete or partial resolution of both AIWS and VM with migraine preventive therapy, while 1 experienced complete resolution of VM but continued to have AIWS. Neuro-otologic abnormalities improved in 2 patients.

conclusionsThis study characterizes the clinical features of AIWS in patients with VM. We observed several rare and highly unusual AIWS misperceptions (frosted-glass vision, underwater vision, dolly zoom effect, sensation of the brain coming out of the head, closed-eye visual hallucinations, and headlight glare-induced marco/microsomatognosia), and resolution or improvement in AIWS and VM with migraine preventive treatment.
