Intervention on the externalization of undercontrolled junior high school students: a school-based randomized controlled trial.
Trial report in BMC public health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundThe study aimed to intervene on personality trait behavior related to the externalization of undercontrolled junior high school students. Undercontrollers are socially maladapted types with high impulsivity and low self-control. Research shows they are at risk for externalizing problems, such as aggressiveness, impulsivity, and antisocial behavior.
methodsA total of 643 students (Boys = 12.39, 55.4% girls) from a junior high school in Dalian participated in the study. The study used latent class analysis to classify 68 undercontrolled junior high school students (10.6%). The experimental group (32 participants) was given 30 systematic experiential intervention activities for 15 weeks, while the control group (30 participants) was given free activities simultaneously. Pre-intervention, post-intervention, and four months post-intervention, participants' externalizing problem behavior and personality scores were tested by the Youth Self-Report and Junior High School Students Personality Development Self-Assessment Questionnaire. The effect of the intervention was tested by repeated-measure ANOVA.
resultAfter one semester of intervention, the intervention effect was significant. The test results of the uncontrolled participants in the experimental group were significantly lower than those in the control group. In the post-test, the personality score of the experimental group was significantly higher than that of the control group.
conclusionsWe discovered that the intervention program could ameliorate the externalizing problem behavior of undercontrolled junior high school students, and demonstrated a sustained promotion effect. CLINICAL TRIAL NUMBER: Not applicable.
