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
Trust in others plays an important role in psychological development. However, longitudinal and developmentally informed research on trust remains limited and fragmented across disciplines. This study aimed to investigate the developmental course of generalized trust from adolescence into young adulthood, and to test sociodemographic, family-level, and peer victimization-related antecedents of trust in an urban cohort. Generalized trust was self-reported at age 13, 15, 17, 20, and 24 in the Zurich Project on Social Development from Childhood to Adulthood (z-proso; n = 1,481). Mean-level and rank-order stability of trust were described. Growth trajectories were modeled using longitudinal linear mixed models (LMMs). Sociodemographic and childhood family-level factors, and longitudinal peer victimization were tested as predictors of trust. Mean-levels of trust followed a curvilinear trajectory characterized by an early decline from age 13 to 17 (Cohen's d = -.48) and a slight increase from age 17 to 24 (d = .11). Rank-order stability of trust increased throughout adolescence (Spearman's r = .40 to 0.58). Notably, socioeconomic disadvantage and migration background were each associated with widening trust disparities over time. Individuals from more disadvantaged backgrounds showed lower and more slowly recovering trust trajectories compared to their more advantaged peers. Maternal trust and parental involvement were associated with higher trust, whereas aversive parenting and parental divorce or separation were linked with lower trust. Peer victimization was associated with lower trust, while increases in peer victimization showed the strongest associations with trust at ages 17 and 20. Generalized trust is a malleable yet increasingly stable construct from adolescence into adulthood. Childhood and adolescent risk and protective factors are important contributors to trust development and should be considered when designing developmentally informed policies and interventions.
