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
introductionDuring the pubertal transition, peer relationships become increasingly salient for adolescents' social and emotional development. However, research on peer contexts during this period has largely emphasized deviant peer groups, leaving the potential role of positive peer affiliations less understood. The present study examined whether positive peer group affiliation mediated associations between pubertal development and social and emotional development.
methodsData were drawn from 1364 youth in the United States (48% female; 76% White; M age = 9.32 years, SD = 0.48 at Wave 3) participating in Grades 4 through 6 of Phase III of the NICHD Study of Early Child Care and Youth Development. Latent growth curve models were used to examine associations among pubertal timing and tempo, positive peer group affiliation, and social and emotional development.
resultsExploratory sex-stratified estimates suggested that earlier pubertal timing was associated with lower initial levels of social and emotional development among boys, but not girls. Across groups, positive peer group affiliation was associated with higher initial levels of social and emotional functioning. Mediation models indicated that pubertal timing was associated with lower positive peer group affiliation for boys, whereas pubertal tempo was associated with declines in peer affiliation over time for girls. However, there was limited evidence that pubertal development or peer affiliation predicted change in social and emotional development over time.
conclusionsFindings suggest that positive peer group affiliation is linked to concurrent social and emotional functioning but does not appear to mediate longitudinal associations between puberty and adjustment.
