Dietary habits and adherence to the Mediterranean diet in a cohort of Parkinson's disease patients in Lithuania.
Article in Frontiers in nutrition, 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: Parkinson's disease (PD) is a neurodegenerative disorder characterized by motor and non-motor symptoms. A growing body of evidence shows that a healthy diet, including the Mediterranean diet (MeDi), can slow the disease progression and improve certain motor and non-motor symptoms. There is limited knowledge about the dietary habits of patients with PD in Lithuania. We aimed to investigate nutritional habits, adherence to the MeDi, related demographic and disease-related factors in Lithuanian PD patients. Methods: The case-control study was conducted at Vilnius University Hospital Santaros Klinikos from 2023 to 2025. A food frequency questionnaire (FFQ) was used to assess dietary habits and construct the MeDi adherence score. Dietary habits and adherence to the MeDi were compared between PD patients and controls. The association between MeDi adherence and the odds of PD, severity of motor and non-motor symptoms, was assessed. Results: A total of 59 patients with PD and 54 healthy controls (HC) were recruited. The MeDi score in the HC group was slightly higher than in the PD group (31.70 vs. 29.62, Conclusion: Patients with PD had different dietary habits compared to controls. However, adherence to the MeDi diet was low in the elderly Lithuanian population (> 65 years), including patients with PD. Higher MeDi adherence was associated with lower odds of PD and selected non-motor symptoms in multivariable analyses.
