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
Theories of personality development emphasize the continuity between who we are as a child and who we are as an adult. The conceptual overlap in influential trait taxonomies designed for children (Rothbart's temperament model) and adults (the Big Five personality) has reinforced theories about developmental continuity, but key hypotheses remain untested because no studies have linked these trait models longitudinally. To bridge this divide, the present study used longitudinal data from a sample of 674 Mexican-origin youth who completed assessments of Rothbart's temperament traits (i.e., Negative Emotionality, Surgency, Affiliation, Effortful Control) from ages 10 to 16 and assessments of Big Five personality traits from ages 14 to 26. Leveraging two waves of overlapping temperament/personality trait assessments at ages 14 and 16, we found the following: (a) continuity between childhood/adolescent temperament and age 26 personality, with the strongest associations between conceptually similar traits, and Effortful Control predicting all Big Five traits (except Extraversion), suggesting self-regulation broadly promotes maturation; (b) temperament starts predicting adult personality traits by age 12-14, consistent with theory positing the temperamental foundations of adult personality crystallize in adolescence; (c) conceptually similar temperament/personality traits reflect different expressions of the same underlying trait from age 10 to 26, established by latent growth models of joint temperament/personality factors; and (d) mean-level personality development across late childhood to adulthood showing that all joint traits maintain consistent rank-order stability and youth increase in Effortful Control/Conscientiousness, decrease in Negative Emotionality/Neuroticism and Surgency/Extraversion, and do not change in Affiliation/Agreeableness. Findings add novel support for widely accepted-yet largely untested-theories, although some unexpected results undermine prevailing assumptions about personality trait development.
