1 · What the graph read from it

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.

2 · The registry

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

There is growing interest about the relation between exposure to artificial light at night (LAN) and mental health. This study aims, for the first time, to explore the association between LAN exposure and neuropsychiatric symptoms in individuals with dementia, investigating its role as a potential environmental risk factor. We collected data about 150 patients with dementia in Modena, Italy. We assessed LAN exposure using satellite imagery, while neuropsychiatric symptoms were evaluated through the Neuropsychiatric Inventory (NPI), a caregiver-administered questionnaire measuring the presence and severity of psychiatric symptoms. We used logistic regression models to examine associations between LAN exposure and neuropsychiatric features. Higher LAN exposure was associated with increased risk of psychiatric symptoms, particularly in the domains of psychosis and sleep disturbances. Specifically, individuals exposed to LAN levels above the median (LAN median = 26.32 nW/cm
