Tectal thickening in pediatric population: Clinical correlates and association with hydrocephalus.
Article in Neurosurgical review, 2026. 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
The tectal plate can be affected by a broad spectrum of pathological processes, resulting in diverse clinical manifestations. These include primary or metastatic tumors, granulomatous diseases, cerebrovascular malformations, ischemic insults, traumatic injury, lipomas, cysticercosis, and degenerative disorders. However, isolated tectal thickening is typically not regarded as a pathological entity and remains insufficiently investigated. This study retrospectively analyzed the clinical and radiological features of 50 patients presenting to the Ankara University Faculty of Medicine between 2012 and 2023 who exhibited tectal thickening on neuroimaging. The objective was to evaluate the association between tectal thickness and clinical symptoms, as well as related radiological pathologies. Clinical data and imaging findings were assessed to investigate correlations between tectal thickening and conditions such as hydrocephalus, Chiari II malformation, syringomyelia, and cerebral atrophy. Statistical analyses were performed to delineate the clinical significance of increased tectal thickness and to explore its potential role in diagnosis and management. All 50 patients demonstrated tectal thickening, with hydrocephalus identified in 76% of cases. Tectal thickness was significantly greater in patients with Chiari II malformation and syringomyelia. However, tectal thickening did not have a statistically significant effect on the area of the cerebral aqueduct. No association was observed between tectal thickening and visual or auditory symptoms. The risk of malignant transformation was found to be low. This study demonstrates a significant association between increased tectal thickness, hydrocephalus, and specific craniospinal pathologies. These findings suggest that tectal thickening may represent a relevant radiological feature associated with distinct clinical and imaging characteristics, warranting further investigation in larger prospective studies.
