Peer Similarity in Physical Activity and Weight Status During Physical Education Class.
Article in American journal of health promotion : AJHP, 2026. 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
PurposeExamined how moderate-to-vigorous physical activity (MVPA) and weight status during physical education (PE) class was related to peer MVPA and weight status.DesignData collected during the first and last weeks of a semester-long PE class.SettingHouston, Texas charter school.ParticipantsAdolescents (n = 156; 13.51 ± 1.45 years old; 52.6% female; 85.4% Hispanic, 14.1% African American, 0.5% Asian) nominated up to 3 female and 3 male students they felt closest to in PE.MeasuresMVPA during PE was assessed by heart rate throughout the semester. Body mass index (BMI) z-score was calculated from height and weight measured at the beginning and end of the semester.AnalysisExponential random graph models explored friendship existence, formation, and maintenance in these networks. Separable temporal exponential random graph models examined how MVPA impacted friendships forming or maintaining over the semester.ResultsStudents with higher MVPA were more likely to receive a new nomination from a student throughout the semester (E = 0.007,
