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
The family systems approach suggests that individuals' psychological processes are shaped within the framework of family interactions. Accordingly, the current study examines the long-term effects of intolerance of uncertainty, irrational happiness beliefs and mistake rumination on family communication within the scope of a semi-longitudinal model. The study analyzed the predictive power of intolerance of uncertainty on irrational happiness beliefs and mistake rumination and whether these variables play a mediating role in family communication. The study, which was conducted in two phases at five-month intervals, included 325 adult participants aged 18-51. Longitudinal serial mediation analysis revealed that intolerance of uncertainty increases irrational happiness beliefs and mistake rumination over time, and these processes negatively affect family communication. The findings suggest that individuals' low tolerance for uncertainty may shape long-term psychological and relational dynamics through family interactions. The study emphasizes the importance of holistic interventions to support the functionality of family systems. In particular, it is suggested that short-term systemic family therapy and emotion-focused individual interventions may be effective in strengthening family communication and increasing the psychological resilience of individuals.
