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

backgroundLight at night (LAN) has been reported to be related to a variety of metabolic diseases, especially in adults. This study aimed to investigate the association between indoor LAN exposure and obesity-related parameters among children and adolescents, and to assess this association at different levels of physical activity.

methodsFrom April to December 2024, LAN exposure was collected by a portable illuminance meter over one week on 628 children and adolescents aged 9-15 years in Shanghai. Obesity-related parameters were measured by body composition analyzer and professional technicians. Moderate-to-vigorous intensity physical activity (MVPA) was assessed using Children' s Leisure Activities Study Survey-Chinese edition (CLASS-C).

resultsMedian indoor LAN

conclusionThis population-based study provides indicates that indoor LAN is significantly related to obesity among children and adolescents. Longitudinal studies are required to confirm the potential moderating role of MVPA between LAN and obesity.
