Effects of pulvinar and combined pulvinar/anterior thalamic deep-brain stimulation on sleep: preliminary results.
Article in Journal of neurology, 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
objectiveTo explore the effect of PuM and combined PuM/ANT DBS on sleep in drug-resistant epilepsy (DRE).
methodsWe retrospectively collected data from DRE patients with PuM-DBS or combined PuM/ANT-DBS and at least one night of EEG recording. Visual scoring of the whole night and quantitative power spectrum analysis on the first and last NREM sleep cycles were performed. We compared sleep characteristics of intra- and inter-patients with PuM-DBS and combined PuM/ANT-DBS.
resultsFive nights were analyzed across three patients. Patient 1 underwent three sequential nights with different DBS settings: ANT + /PuM + , ANT + /PuM-, and ANT + /PuM + . ANT-DBS, either alone or in combination, was associated with disrupted sleep architecture, particularly in the latter part of the night. Visual staging showed no clear differences over the nights. Quantitative analysis however showed a worst sleep architecture in the last NREM cycle, as disclosed by a lower normalized delta power, in the second night (ANT + /PuM-) compared with the first and third nights (ANT + /PuM +). In patients with PuM-DBS alone, in cyclic or continuous stimulation modalities, sleep structure appeared preserved, with normal sleep efficiency and a normalized delta power higher than that of patient one. SIGNIFICANCE: PuM-DBS, compared to ANT-DBS, appeared not to disrupt sleep architecture.
