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 evaluated the Olweus Bully Prevention Program (OBPP) in urban middle schools serving a mostly African American student population. Participants were 1791 students from three communities with high rates of crime and poverty. We evaluated the impact of the OBPP using a multiple-baseline experimental design in which we randomized the order and timing of intervention activities across three schools. We assessed the frequency of violence and victimization using self-report and teachers' ratings of students collected every 3 months over 5 years. Initiation of the OBPP was associated with reductions in teachers' ratings of students' frequency of aggression, with effects emerging in different years of implementation for different forms of aggression. Whereas reductions in teachers' ratings of students' verbal and relational aggression and victimization were evident during the second implementation year, reductions in physical aggression did not appear until the third year. Effects were consistent across gender and schools, with variability across grades for relational and verbal aggression and victimization. In contrast, there were no intervention effects on students' reports of their behavior. Positive outcomes for teachers', but not students' ratings, suggest the intervention's effects may have been limited to the school context. Variation in when effects emerged across outcomes suggests that changes in physical aggression may require more sustained intervention efforts. The intervention was also associated with increases in teachers' concerns about school safety problems, which may indicate that teachers were more attuned to recognizing problem behaviors following exposure to the OBPP.
