The Spectrum of Inherited Gray Matter Degenerative Brain Disorders (DBD) in Children: A Single-Center Study.
Article in Annals of Indian Academy of Neurology. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
Objectives: To study the clinical spectrum of inherited gray matter degenerative brain disorders (DBD) in children. Methods: This cross-sectional study evaluated children up to 12 y of age, diagnosed with an inherited gray matter DBD in a tertiary care pediatric hospital between July 2019 and December 2020. Results: A total of 314 children with progressive neuroregression were screened. Of these, 117 children with inherited gray matter DBD were included in the study. The clinic-based prevalence of DBD was 8.2%, and inherited gray matter DBD was 3.1%. The proportion of the inherited gray matter DBD was 37.3% among the overall DBD cases. Children were categorized into three groups based on the age at onset of disease: below 2 years (N = 57, 48.7%), between 2 and 5 years (N = 32, 27.3%), and between 6 and 12 years (N = 28, 23.9%). Based on the predominant cerebral structure involved, gray matter DBD were classified as cerebral gray matter disorders (53%), basal ganglia disorders (34.1%), and cerebellar disorders (12.8%). Overall, the most common disorders were Wilson disease (18%), neuronal ceroid lipofuscinosis (NCL) (17%), and neurodegeneration with brain iron accumulation (NBIA) (16%). The most common gray matter DBD in children <2 years of age were NBIA (n = 11), Rett syndrome (n = 11), and gangliosidoses (n = 10). NCL (n = 14) and ataxia telangiectasia (n = 6) were most common in the age group of 2-5 years. Wilson disease (n = 19) was the most common disorder in the age group of 6-12 years followed by NCL (n = 4) and NBIA (n = 3). Conclusion: Our study highlights the burden and spectrum of gray matter DBD in children. The clinic-based prevalence of DBD was 8.2%, and of inherited gray matter DBD was 3.1%. The proportion of inherited gray matter DBD was 37.3% among the overall DBD cases. Wilson disease, NCL, and NBIA are the most common gray matter DBD in children. Timely diagnosis is important for the prevention of recurrence in subsequent pregnancies.
