Patient-Reported Communication Decline Following Deep Brain Stimulation in Parkinson's Disease.
Article in Movement disorders clinical practice, 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
backgroundObjective decline in communication abilities following Deep Brain Stimulation (DBS) in People with Parkinson's disease (PwP) is common; however, patient perspectives remain under-investigated.
objectivesThis study examined subjective change in communicative efficacy using the Communicative Participation Item Bank (CPIB) in PwP following DBS.
methodsThis study examined change in CPIB in 30 PwP following subthalamic DBS using t-tests and examined correlates with cognition.
resultsStatistically significant declines in subjective communication efficacy were reported following DBS, t(29) = -3.19, P = 0.003. CPIB decline was not associated with baseline or change in objective language performance after DBS. CPIB decline was not related to laterality of DBS target or pre-DBS cognitive status.
conclusionsSubjective communication decline is common in PwP who undergo STN-DBS, but was not associated with objective measures of language and cognition. Findings support incorporating patient-reported outcomes (eg, CPIB) into DBS evaluations to inform intervention and clarify risk factors for communication decline.
