Demographics, treatment patterns, and healthcare resource utilization in Parkinson's disease: a real-world data study using a claims database.
Observational study in Arquivos de neuro-psiquiatria, 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
Parkinson's disease (PD) is a progressive neurodegenerative disorder associated with substantial disability, morbidity, and mortality. Timely diagnosis and treatment are essential to mitigate its impact. Despite its burden, real-world data on PD in Brazil remain limited.To describe the demographic and clinical profile of individuals with PD treated in the Brazilian public healthcare system and to evaluate patterns of treatment and healthcare resource utilization (HCRU).The present observational, retrospective, longitudinal study analyzed data from the Brazilian public healthcare system (Sistema Único de Saúde, SUS, in Portuguese) between January 2013 and December 2022. Patients aged ≥ 20 years with at least 2 core procedures coded for PD (ICD-10 G20) were included. Inpatient and outpatient datasets were analyzed separately.A total of 53,674 PD patients were identified. The mean age at diagnosis was 65.4 years, with a slight male predominance (53.0%). Most patients (47.0%) had more than 6 outpatient visits, and 44.4% had 1 or 2 hospitalizations. The most frequent procedures were PD treatment (inpatient) and physical therapy (outpatient). The most used medications were pramipexole (45.6%), amantadine (26.0%), and entacapone (17.1%).The present study provides valuable insights into the demographic and clinical profile of PD patients in Brazil, highlighting frequent procedures and treatment patterns. A key limitation is the non-capture of basic PD medications, such as levodopa, which are often dispensed outside the analyzed datasets. These findings underscore the need for improved data integration and access to comprehensive PD care within the public health system.
