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

Mucopolysaccharidoses (MPS) are a group of inherited metabolic diseases associated with impaired lysosomal degradation of glycosaminoglycans. The aim of this manuscript is to report a case of a patient with mucopolysaccharidosis type IIIC (MPS IIIC) diagnosed at 12 years of age - to raise awareness among pediatricians, pediatric neurologists, and endocrinologists about the possible misdiagnosis. The patient was initially diagnosed with autism spectrum disorder and hyperactivity with normal motor development. During follow-up, psychomotor regression with moderate intellectual disability was observed. The patient was referred for further metabolic work-up only after the results of molecular analysis suggesting MPS IIIC. The final diagnosis was established based on clinical, biochemical, and molecular analyses.
