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

A 24-year-old female patient with a 4-year history of recurrent abdominal pain, diarrhea, periodic fever and elevated C-reactive protein was referred to our institution. Colonoscopy, esophago-gastro-duodenoscopy, capsule endoscopy and contrast-enhanced CT showed no significant findings. Because she and her mother had sensorineural hearing loss, a diagnosis of cryopyrin-associated periodic syndrome was suspected. Genetic testing of the patient and her mother revealed a candidate germline variant of NLRP3. The patient was commenced on subcutaneous 150 mg canakinumab, a fully human monoclonal antibody targeting IL-1β, at a dose of 150 mg every 8 weeks, which resulted in the persistence of sensorineural hearing loss but led to the complete disappearance of her abdominal symptoms and periodic fever.
