Intergenerational trauma in forcibly-displaced populations in Latin America: a scoping review.
Article in BMC public health, 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
backgroundOverlapping humanitarian crises make the Americas home to one in every five forcibly displaced or stateless persons worldwide. Although a robust body of literature describes the intergenerational effects of traumatic experiences related to forced displacement, evidence from Latin America and the Caribbean (LAC) and with Latinx groups is scarce and contains wide variations in operationalizations of intergenerational trauma, transmission mechanisms and coping strategies. The aim of this scoping review was to improve our understanding of intergenerational trauma in forcibly displaced populations from LAC. We addressed these objectives: (i) to map existing literature on intergenerational trauma in forcibly displaced groups in LAC; (ii) to identify operationalizations of intergenerational trauma, transmission mechanisms and coping strategies in forcibly displaced groups in LAC; and (iii) to identify knowledge gaps.
methodsSystematic searches were conducted in 20 online databases to identify articles that studied intergenerational trauma, associated transmission mechanisms and coping strategies in forcibly displaced Latinx groups originating in LAC. Narrative analysis was conducted to describe the relevant themes extracted from the included literature.
resultsSix English and Spanish-language articles were included, from which three general themes were identified regarding intergenerational trauma in forcibly-displaced Latinx populations: (i) intergenerational trauma operationalizations, (ii) transmission mechanisms and coping strategies, and (iii) identified gaps in research and evidence. Two subthemes themes were identified relating to intergenerational trauma operationalizations: (i) measures and samples, (ii) forced displacement motives. Evidence gaps in the literature were also elaborated.
conclusionWe identified gaps in intergenerational trauma definitions and operationalizations. Greater methodological rigor and consistency in trauma reporting is warranted to support future evidence-based research and inform supportive systems that promote the health of forcibly-displaced populations and their descendants in the Americas.
