Tailored light intervention for sleep and cognition in World Trade Center (WTC) cohort.
Article in Archives of environmental & occupational health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
World Trade Center rescue and recovery workers and volunteers (WTC RRWV) are vulnerable to circadian rhythm disruption due to stress and environmental exposures during the 9/11 operation, with high rates of cognitive impairment and poor sleep quality. This exploratory pilot study assessed the feasibility and preliminary effect of a 12-week light-based intervention targeting sleep and cognition. Twenty-three WTC RRWV aged ≥50 years with mild cognitive impairment and sleep disturbances completed the intervention. Sleep, cognition, and circadian-effective light exposures were measured pre-and post-intervention using actigraphy, Pittsburgh Sleep Quality Index, cognitive tasks (go/no-go, digit span, Stroop), and a Daysimeter. Results showed significant improvements in sleep quality and cognitive performance. Greater circadian-effective light exposure was positively associated with improved cognitive accuracy. These preliminary observations suggest that light-based interventions may enhance sleep and cognitive function in at-risk populations.
