Driving impairment in patients with movement disorders: examining the Baylor driving questionnaire by objective driving assessment.
Article in Clinical parkinsonism & related disorders, 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
Background: The development of a screening tool to identify driving impairment in patients with movement disorders is an unmet need. Objective: To validate Baylor Driving Questionnaire for Movement Disorders (BDQMD) by objective driving assessment (ODA). Methods: In this cross-sectional study, 142 patients with various movement disorders completed the 10-item BDQMD and of those, 25 completed ODA using the driver performance analysis system (DPAS). Results: The mean total BDQMD score for the whole cohort was 14.7 ± 5.6 (range 10-47). Patients who underwent ODA had a mean BDQMD score of 12.8 ± 2.9. Four had minimum driving skill, 20 had average, and 1 was highly skilled. Total BDQMD negatively correlated with overall DPAS score (r = -0.45, p = 0.025) and the score reflecting the traffic risk analysis (r = -0.41, p = 0.041). Conclusion: BDQMD total score in this pilot study correlated well with the performance in ODA. Additional validation studies are warranted to explore its potential as a screening tool for driving impairment.
