1 · What the graph read from it

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.

2 · The registry

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

Although the association between adolescents’ sibling relationships and depressive symptoms has been investigated, the within-person bidirectional dynamics between these constructs have remained unclear. Additionally, few studies have examined whether and how sibling structure moderates these associations. To address these gaps, the present study utilized four-wave longitudinal data collected at six-month intervals from 1,927 Chinese adolescents (Mage = 13.67, SDage = 1.69; 50.06% female). Using a random-intercept cross-lagged panel model, the current study examined the within-person bidirectional dynamics linking sibling warmth, conflict, and rivalry with depressive symptoms, as well as the potential moderating effects of sibling gender composition and age difference. The results revealed significant within-person bidirectional dynamics between sibling conflict and depressive symptoms. In contrast, changes in sibling warmth and rivalry did not predict changes in depressive symptoms, but were instead predicted by them at the within-person level. These associations were not moderated by sibling gender composition or age difference. This study provides empirical evidence for the within-person bidirectional dynamics between sibling relationships and depressive symptoms, highlights the important role of sibling conflict in this process, and suggests that interventions or family education aimed at reducing sibling conflict may help reduce adolescents’ depressive symptoms while also indirectly supporting other dimensions of sibling relationships.
