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

Introduction: With the rapid development of their countries, Chinese young people today face intense stress. Some cope by striving for high-quality resources (involution), while others adopt a passive approach, lowering their desires (lying flat). This study explores the relationship between lying flat and problematic smartphone use (PSU), focusing on the role of self-esteem. Methods: We conducted three studies ( Results: The studies demonstrated a significant relationship between lying flat and PSU, with self-esteem serving as a mediator. Additionally, Study 3 showed a causal effect of self-esteem on smartphone use desire. Discussion: These findings provide insight into why and how lying flat affects self-esteem and smartphone use behaviors and desires, highlighting the psychological mechanisms behind the trends observed in Chinese youth.
