Trajectories and correlates of Latino/a children's sibling relationships.
Article in Developmental psychology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
This study contributes to research on the patterns of change in, and parent-child relationship correlates of, sibling relationships in Latino/a children in middle childhood and early adolescence. Specifically, the study goals were to (a) chart age-related trajectories of sibling intimacy and conflict between 6 and 12 years of age using a cohort-sequential accelerated longitudinal design and (b) examine between-person and within-person associations with parent-child warmth and conflict. Data were collected from a three-cohort study of 285 Latino sibling pairs and their caregivers, who participated at three time points over an 18-month period in a randomized clinical trial. Results of multilevel longitudinal growth models revealed a quadratic effect of sibling intimacy, with moderation by child sex, and a linear effect of sibling conflict, moderated by mother nativity. Findings of multilevel models further revealed that mother-child (but not father-child) warmth was linked to sibling intimacy, suggesting that higher maternal warmth was related to greater sibling intimacy, on average, across time (between-person effect). Regarding conflict, there was a significant between-person effect of father-child conflict on sibling conflict, with higher average father-child conflict associated with higher sibling conflict over time. A within-person effect of mother-child conflict on sibling conflict revealed that on occasions when mothers reported greater conflict with their children than usual, children reported more sibling conflict. The discussion considers age-related changes in sibling relationships and the interplay of family dynamics in Latino families during middle childhood and the transition to adolescence.
