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
Several studies have explored sleep discrepancy as a key to understanding insomnia, linking it to attentional bias, arousal, distorted processing, depression, and anxiety. However, further research is needed to understand whether discrepancies in sleep perceptions observed in a community-dwelling middle-aged population, vulnerable to stress, were related to mood and other social factors. We used self-report questionnaires and smart watches to investigate the discrepancies between perception of sleep and objective data among 32 community-dwelling middle-aged individuals. We analyzed the relationship between sleep discrepancies and psychosocial factors and compared emotional state scores across different sleep tendencies to examine whether sleep discrepancy could serve as a potential indicator for identifying variations in psychological well-being. Emotional states associated with sleep discrepancy perception among middle-aged adults included tension-anxiety (TA) (r = -0.361), depression-dejection (r = -0.475), and total mood disturbance (TMD) (r = -0.287). In the regression model, sex, TMD, and self-rated health were significant predictors of perceived sleep discrepancy (adjusted R
