The Effects of Color Therapy on Fatigue, Depression, and Quality of Life in Parkinson's Patients: A Randomized Controlled Trial.
Trial report in Brain and behavior, 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
backgroundWhen compared with healthy people, fatigue, depression, and a lower quality of life are frequently experienced by Parkinson's patients. Color therapy has effects such as reducing depression and improving focusing problems.
aimExamining the effects of color therapy on fatigue, depression, and quality of life in Parkinson's patients constitutes the aim of the present study.
methodThis randomized controlled trial was conducted with 60 Parkinson's patients (30 intervention, 30 control). In the first and second weeks, the intervention group received color therapy 3 days per week, consisting of 15-min exposures to purple, yellow, and orange light (totaling 45 min per session). No intervention was performed during the third and fourth weeks. In the fifth and seventh weeks, a single weekly session was administered, applying each color for 15 min (totaling 45 min), while no intervention was carried out in the sixth week. Post-test data were collected in the eighth week. The control group received no intervention. Data collection tools included a "Patient Information Form," "Parkinson Fatigue Scale (PFS-16)," "Beck Depression Inventory (BDI)," and "SF-36 Quality of Life Scale."
resultsThe total mean score and sub-dimension scores of PFS-16 and the total mean score of BDI decreased statistically significantly in the intervention group (p = 0.05). The intervention also caused a significant increase in SF-36 quality of life total score and sub-dimension mean scores of the intervention group (p < 0.05).
conclusionColor therapy application was found to decrease the level of fatigue and depression and improve the quality of life in Parkinson's patients.
