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
Background: Sleep disturbances are common among military personnel stationed in high-altitude environments and may have important implications for health and operational functioning. This study aimed to investigate the effects of cumulative high-altitude exposure on sleep quality and to examine the roles of oxygen supplementation and frequency of returning to low-altitude areas. Methods: A cross-sectional survey was conducted among 1,316 military personnel stationed in high-altitude regions. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI), with higher scores indicating poorer sleep quality. Participants also reported demographic characteristics, cumulative duration of high-altitude residence, oxygen supplementation frequency, oxygen supplementation duration per session, and frequency of returning to low-altitude areas. Bivariate correlation analyses and hierarchical regression analyses were conducted to examine the associations and interaction effects among these variables. Results: Sleep difficulties were positively correlated with cumulative high-altitude residence duration ( Conclusion: These findings suggest that optimizing oxygen supplementation strategies and managing altitude-transition frequency may help reduce sleep disturbances and improve overall health outcomes among military personnel in high-altitude environments.
