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
This study aimed to identify latent profiles of mental health among Chinese senior high school students using latent profile analysis (LPA), and to examine the associations through which problematic smartphone use (PSU) is linked to mental health, focusing on the mediating role of emotional growth mindset (EGM) and the moderating role of left-behind experience (LBE). Using a dual-factor model of mental health as the conceptual basis for identifying mental health profiles, a cross-sectional survey was conducted of 34,831 students in Grades 10-12 in Tianmen, China. Validated scales were used to assess PSU, EGM, subjective well-being and depressive symptoms. LPA identified four distinct mental health profiles: very low depression-high well-being, low depression-moderate well-being, moderate depression-moderate well-being and high depression-low well-being. PSU was directly associated with poorer mental health and showed an indirect association through EGM. LBE moderated the first stage of the mediation pathway, that is, the PSU-EGM association, with a stronger effect observed among students with LBE.
