Home-Based Tailored Light Therapy for Sleep, Mood, and Cognitive Outcomes in Mild Cognitive Impairment: A Randomized Trial.
Article in Journal of applied gerontology : the official journal of the Southern Gerontological Society, 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
BackgroundLight offers a promising approach to sleep and circadian disturbances in mild cognitive impairment (MCI).ObjectiveTest a home-based lighting intervention in people living with MCI.MethodsIn a randomized, placebo-controlled trial, 61 participants received active or placebo light for 24 weeks, with assessments for cognition, sleep, depression, and quality of life at baseline, week 13, 25, and, post-intervention, at week 37. Light exposure was measured as area under the curve (AUC) for morning circadian stimulus (CS).ResultsActive light participants (mean age 69.7 years; 52% male; mean MoCA 21.4) showed greater improvement in ADAS-Cog memory scores than placebo (
