Health-Related Quality of Life in Relation to the 5-2-1 Criteria in Parkinson's Disease in Sweden.
Article in Movement disorders clinical practice, 2025. 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
backgroundDevice-aided therapies (DAT) offer alternatives to oral or transdermal dopaminergic treatments in advanced Parkinson's disease (PD), where they can reduce motor fluctuations and dyskinesia and improve health-related quality of life (HRQoL). The 5-2-1 criteria can be seen as a rough indicator when DAT might be considered, that is, when a patient has daily ≥2 hours off and/or ≥1 hour troublesome dyskinesia despite ≥5 daily oral levodopa intakes.
objectivesThe objective was to analyze differences in HRQoL and clinical outcomes in patients fulfilling and not fulfilling the 5-2-1 criteria.
methodsPatients from three different regions in Sweden, registered in the National Parkinson's Disease Patient Registry (PARKreg), with registrations in off hours, dyskinesia hours, and Parkinson's Disease Questionnaire-8 (PDQ-8) score were included. The generic QoL questionnaire EQ-5D was also evaluated. Data from PARKreg was complemented with data from a medical record review.
resultsIn total, 396 (36%) of 1085 patients with sufficient information met the 5-2-1 criteria. Patients meeting the criteria had a significantly lower HRQoL, as measured by PDQ-8 and EQ-5D, compared to those not meeting the criteria. Each additional hour spent in off or with dyskinesia was associated with lower HRQoL, where time in off state had the strongest impact.
conclusionsThe 5-2-1 criteria identified patients with high disease burden and poor QoL, in combination with motor fluctuations and/or dyskinesia. This delineates a group of patients for whom further investigation for DAT candidacy or other optimizations of treatments may be indicated.
