The Relationship between PDQ-8 and Costs in Parkinson's Disease-A Swedish Register-Based Study.
Article in Movement disorders clinical practice, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Background: Parkinson's disease (PD) is a progressive neurodegenerative disorder associated with substantial costs which increase with progression state. However, few studies have investigated the association between costs and health related quality of life. Objectives: To estimate the relationship between costs and health related quality of life, measured by the Parkinson's disease Quality of Life Questionnaire (PDQ)-8 from a societal perspective, partial societal perspective (excluding productivity loss), and a health care perspective. Methods: The Swedish Parkinson's Disease registry was linked to health care data registries to estimate annual costs. A generalized linear model was used to assess the relationship between instrument items and costs. Results: The results suggest that PDQ-8 captures the increase of costs by PD severity, particularly for costs within the broader societal perspective. From the best to worst PDQ-8 quartile, we observed approximately 7-fold increases within the societal perspective (39,400 to 274,300 SEK) and the partial societal perspective (31,800 to 219,400 SEK), and the increase within the health care perspective more than doubled (21,900 to 49,700 SEK). The PDQ-8 dimensions "mobility," "activities of daily living" and "social support" were associated with high costs in all perspectives. Conclusion: Using a disease-specific measure reflecting the patient's perspective, we found an increase of costs with worsening severity of PD, particularly for costs within the broader societal perspective. High costs were associated with not only motor symptoms, but also the dimension "Social support."
