Alterations of thalamic nuclei volumes in patients with cluster headache.
Article in Neuroradiology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
purposeThis study aimed to compare the alterations of thalamic nuclei volumes and the intrinsic thalamic network in patients with cluster headache and healthy controls.
methodsWe retrospectively enrolled 24 patients with episodic cluster headache and 24 healthy controls. We calculated the thalamic nuclei volumes in the patients with cluster headache and healthy controls based on three-dimensional T1-weighted imaging with automated segmentation using the FreeSurfer program. We also investigated the intrinsic thalamic network using structural co-variance analysis based on the thalamic nuclei volumes and graph theory under the BRAPH program. We compared the thalamic nuclei volumes and intrinsic thalamic networks in patients with cluster headaches and healthy controls.
resultsThe right and left whole thalamic volumes did not differ in the patients with cluster headaches and healthy controls (0.4199 vs. 0.4069%, p = 0.2008; 0.4386 vs. 0.4273%, p = 0.3437; respectively). However, there were significant alterations of right and left medial geniculate nuclei volumes in the patients with cluster headaches and the healthy controls. The right and left medial geniculate nuclei volumes of the patients with cluster headaches were greater than those of the healthy controls (0.0088 vs. 0.0075%, p < 0.0001; 0.0086 vs. 0.0072%, p < 0.0001; respectively). The intrinsic thalamic networks of the groups were not different.
conclusionThis study demonstrates significant alterations in the bilateral medial geniculate nuclei volumes in patients with cluster headache compared to healthy controls. These alterations may be related to the pathophysiology of cluster headache. However, there are no changes in the intrinsic thalamic network in patients with cluster headache.
