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
objectiveThis study estimated the prevalence of problematic smartphone use (PSU) among multicultural adolescents and examined its association with major mental health indicators.
methodsWe conducted a cross-sectional analysis of the 2020 Korea Youth Risk Behavior Web-based Survey, which included 1,065 adolescents from multicultural families. PSU was assessed via the validated Korean version of the Smartphone Overdependence Scale. The mental health variables included perceived stress, loneliness, anxiety symptoms, and suicidal ideation, plans, and attempts. Multivariate logistic regression models were used to identify factors associated with PSU. Structural equation modeling (SEM) was applied to evaluate the direct associations between PSU and mental health outcomes and to test the moderating effects of key demographic and psychosocial factors.
resultsThe prevalence of PSU among multicultural adolescents was 26.2%. Compared with adolescents not in the PSU group, those in the PSU group more frequently reported high perceived stress, frequent loneliness, elevated anxiety symptoms, and suicidal ideation. In adjusted models, PSU was independently associated with higher odds of stress, loneliness, anxiety, and suicidal planning, as well as lower academic achievement. The SEM findings supported significant associations between PSU and multiple mental health indicators, with some associations being stronger among girls, adolescents from lower-income households, and those experiencing higher levels of stress or loneliness.
conclusionAmong Korean multicultural adolescents, PSU is common and is associated with multiple adverse mental health and poorer academic self-perceptions. These findings underscore the importance of culturally sensitive strategies that address both digital media use and psychosocial well-being among multicultural adolescents.
