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.

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
Introduction: Although marriage generally supports psychological wellbeing, individuals can still experience profound loneliness within intimate relationships, which may increase susceptibility to adverse mental health outcomes. This study employed a cross-sectional, dyadic research design to investigate whether the belief that happiness is fragile mediates the relationship between marital loneliness and depression sensitivity. Methods: Self-report data were collected from 307 married couples ( Results: Results revealed significant actor and partner mediation effects for both husbands and wives (e.g., actor effect: β = 0.39, Discussion: These findings illustrate how cognitive appraisals of happiness transmit relational loneliness into depressive vulnerabilities. Addressing maladaptive beliefs about the fragility of happiness in couple therapy may help prevent marital loneliness from exacerbating depressive symptoms for both partners.
