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

backgroundNeuroferritinopathy (NF) is a rare autosomal dominant disease caused by mutations in the ferritin light chain 1 (FTL1) gene leading to abnormal excessive iron accumulation in the brain, predominantly in the basal ganglia.

methodsA literature search was performed on Pubmed, for English-language articles, utilizing the terms iron metabolism, neurodegeneration with brain iron accumulation, and NF. The relevant articles were reviewed with a focus on the pathophysiology, clinical presentation, differential diagnoses, and management of NF.

resultsThere have been nine reported mutations worldwide in the FTL1 gene in 90 patients, the most common mutation being 460InsA. Chorea and dystonia are the most common presenting symptoms in NF. There are specific features, which appear to depend upon the genetic mutation. We discuss the occurrence of specific mutations in various regions along with their associated presenting phenomenology. We have compared and contrasted the commonly occurring syndromes in the differential diagnosis of NF to guide the clinician. DISCUSSION: NF must be considered in patients presenting clinically as a progressive movement disorder with variable phenotype and imaging evidence of iron deposition within the brain, decreased serum ferritin, and negative genetic testing for other more common movement disorders such as Huntington's disease. In the absence of a disease-specific treatment, symptomatic drug therapy for specific movement disorders may be used, although with variable success.
