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 aimed to expand knowledge on the roles of psychological inflexibility and school friendship closeness in adolescents' loneliness during the transition to upper secondary education. The participants were 885 Finnish adolescents (mean age = 15.74, SD = 0.37, 56% girls). Loneliness was measured twice: in Grade 9 and at the beginning of upper secondary school in 10th grade. Psychological inflexibility and the closeness of friendships in school were measured in Grade 9. Results showed that a high level of psychological inflexibility in Grade 9 was associated with higher loneliness at the beginning of upper secondary education and increased loneliness during the educational transition. Furthermore, girls' (but not boys') friendship closeness in school partly mediated the association between psychological inflexibility and loneliness. The results suggested that psychological inflexibility is a social risk factor for loneliness among adolescents transitioning to upper secondary school. Enhancing psychological flexibility skills could thus make an important contribution to the promotion of adolescent peer relationships and prevention of loneliness.
