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
Background: Adrenoleukodystrophy (ALD) is an intriguing disease with a heterogeneous clinico-radiological profile. Behavioral and cognitive impairments are often the initial and predominant manifestations, yet their patterns are frequently overlooked. This study aims to elaborate on the patterns of cognitive dysfunction, behavioral changes, and movement disorders in ALD to facilitate its earlier diagnosis. Methods: In this case series, 12 cases of ALD were assessed and evaluated for cognitive, behavioral, and movement abnormalities to identify patterns of involvement. Results: All patients were male, with an age range of 5-46 years. 75% presented with cerebral ALD (CALD), and 25% had an adrenomyeloneuropathy phenotype. Cognitive dysfunction, behavioral changes, and seizures were observed in 75%, 66.7%, and 33.3% of ALD patients. An initial posterior to anterior pattern of progression of cognitive impairment dominated by higher-order visual dysfunction and language regression was observed in 66.7% of CALD patients, while a frontal pattern was noted in 22.2% of CALD patients. While cognitive impairment typically indicated dysfunction of occipito-parieto-temporal networks, behavioral changes predominantly suggested dysfunctional fronto-temporal-subcortical connections. A novel observation was the occurrence of tics and stereotypies in 33.3% of ALD patients. Conclusion: This study describes the patterns of cognitive, behavioral, and movement abnormalities in ALD and highlights the contributory role of dysfunctional white matter networks. Cognitive patterns predominantly reflect a posterior-to-anterior gradient of impairment of white matter connections, while behavioral markers indicate involvement of fronto-temporal-subcortical networks. Adding to this spectrum, the occurrence of tics and stereotypies is a unique observation in ALD.
