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

introductionIn search of disease-modifying treatments for the Niemann-Pick disease type C (NPC), this Phase II single-arm clinical trial evaluated the safety and efficacy of efavirenz, a reverse transcriptase inhibitor that potentially ameliorates neuronal cholesterol turnover, typically impaired in this rare lysosomal storage disorder. MATERIAL AND

methodsPatients 14 years of age or older with genetically confirmed NPC received efavirenz 25 mg/day (Weeks 1-26) or 100 mg/day (Weeks 27-52) orally on top of standard care including miglustat. The primary endpoint was the proportion of response, defined as lack of deterioration in a composite outcome of cognitive performance. Secondary endpoints included the quantitative scores of several clinical neuropsychological assessment tools, some relevant neurological signs and symptoms, and imaging and biological specimen-based biomarkers. Measures were taken repeatedly over time and were analyzed using generalized linear mixed models.

resultsSixteen patients 15-60 years of age were enrolled. All (100.0 %, 95 % exact confidence interval: 79.4-100.0 %) met the primary endpoint response criterion at Week 52. Quantitative neuropsychological assessments yielded more nuanced results, with relative preservation of learning, memory and executive control, and subtle impairments of verbal fluency, selective and divided attention, and cognitive inhibition. Some patients had better responses than others, allowing us to set two well-differentiated subgroups that differed essentially in the time since symptoms onset. No efavirenz-related or serious adverse events were reported.

conclusionEfavirenz appears to be a safe, easy-to-use, new targeted therapeutic option which slows the rate of NPC progression. The benefits of efavirenz are greater if started earlier.
