Identifying individuals at-risk of developing Parkinson's disease using a population-based recruitment strategy: The Healthy Brain Ageing Kassel Study.
Article in NPJ Parkinson's disease, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Neurodegeneration in Parkinson's disease (PD) occurs before motor features develop: assessing risk factors and identifying prodromal markers is necessary to recruit prodromal cohorts, improve early diagnosis, and develop preventive therapies. As part of Healthy Brain Ageing (HeBA), we implemented a stepwise, population-based screening to identify people at high risk of developing PD. Residents (n = 158,818; 50-80 years) in and around Kassel, Germany were invited to complete an online survey with questions for prodromal symptoms and risk factors. An individual risk score was calculated (International Parkinson and Movement Disorder Society criteria). Selected individuals received a smell test. 8001 of 8774 survey responses were valid; the response rate to the smell test mailings (n = 3021) was 90%. Hyposmic participants (n = 1019) had more subjective hyposmia and subjective memory impairment (p < 0.01). Follow-up visits will validate the recruitment strategy and monitor conversion to manifest PD. Our recruitment strategy identifies people who might be at risk for PD.
