Ethnic and Gender Disparities in Access to Deep Brain Stimulation Surgery for 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. Cited by 5 papers.
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
backgroundDeep brain stimulation (DBS) is an established treatment for Parkinson's disease (PD) in appropriately selected patients. DBS may be underused in certain patient populations, especially women and racialized groups. Barriers and biases to receiving DBS that could account for underuse among these groups are not well studied in Canada.
objectiveWe aim to better characterize the disparities in gender, ethnicity and other demographic factors among patients referred for and receiving DBS.
methodsWe performed a retrospective chart review and phone survey of DBS patients treated at two Canadian centers and from Canada Open Parkinson Network (C-OPN). Gender, ethnicity, marital status, native language, birth country, urban versus rural residency, level of education, household income and mode of referral were studied.
resultsAmong all participants, more men than women received DBS. Most patients (81.8-94.1%) in both referral and implanted groups were White. The gender and ethnicity of this cohort do not represent Canadian demographics. Patients referred and receiving surgery had higher educational level compared with general Canadian population. Being married was positively associated with DBS referral and implantation.
conclusionSignificant ethnic and gender disparities in receiving DBS exist. Educated White men were overrepresented. Further actions need to be taken to expand the accessibility of this important treatment to all eligible PD patients with an effort to provide equitable care to women, racialized groups and those who cannot advocate for themselves in Canada.
