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
Collective intergenerational trauma is a complex phenomenon affecting descendants and families exposed to the enduring effects of collective traumatic events, such as forced displacement, genocide and war. This systematic review aimed to explore the mechanisms through which collective trauma is transmitted across generations, examine its consequences for children and families, and critically analyse interventions employed by health professionals and social workers. A systematic review was conducted using ScienceDirect, Wiley Online Library and PubMed. Studies published between 2016 and 2026 were screened for eligibility, resulting in the inclusion of 22 studies. The indexing terms "collective intergenerational trauma", "collective transgenerational trauma", "trauma transmission", "transmission mechanisms", "consequences", "intergenerational trauma interventions", "Social Care", and "Health Professionals", were used, along with the Boolean operators AND and OR. The included studies were synthesised using thematic analysis. The findings indicate that collective intergenerational trauma is transmitted through interacting family, communicative, sociocultural and biological mechanisms. Its consequences include psychological and psychosocial difficulties among descendants, disruptions in family relationships and adverse effects on family functioning. Existing interventions primarily focus on individual trauma, with limited attention to its collective and intergenerational dimensions. The findings highlight the need for culturally responsive, trauma-informed and family-centred interventions addressing collective intergenerational trauma within a systemic framework. Health professionals and social workers can play an important role in promoting mental health, strengthening resilience, mitigating the long-term effects of trauma and supporting affected children, families and communities.
