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

importanceTangier disease (TD) is an ultra-rare disease, characterised by progressive peripheral neuropathy with no established treatment.

objectivesTo determine whether miglustat improved the clinical status of a single patient with TD, and to investigate the possible mechanisms of miglustat in this patient. DESIGN, SETTING, AND

participantsAn n-of-1 ABAB study, alternating on and off treatment for 6-month periods, total study duration of 2 years with an additional compassionate-access period of 21 months. EXPOSURE: Miglustat, an orphan drug licenced to treat Gaucher disease and Niemann-Pick disease, was repurposed. MAIN OUTCOMES AND MEASURES: The study was designed with two co-primary endpoints: (a) time taken to complete the nine-hole peg test (fine motor control and finger dexterity), and (b) hand strength: grip and three-point pinch strength tests. Secondary endpoints were quality-of-life measures and biomarkers.

resultsA 21-year-old (at baseline) left-handed male patient with TD, diagnosed at the age of 6 months, and disabling neuropathy was included in the study. Over 2 years, there was a small signal in our clinical measures that the drug may be beneficial. Compared with the 2 years prior to treatment, the patient had no relapse of neuropathy during his study period and further extension. During the 21-month treatment extension, he showed considerable improvement on primary endpoints. Biomarkers changed as expected based on the mechanism of action of miglustat. Nerve conduction studies showed a mild benefit. Importantly, the patient's reported experience suggested a meaningful benefit from miglustat. CONCLUSIONS AND RELEVANCE: Miglustat may be used to treat neurological complications of TD. This study showed that an n-of-1 study to inform a policy decision is practical and may offer hope to patients with rare diseases.
