Transgenerational transfer of genocidal trauma: a systematic review and meta-analysis.

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 meta-analysis aims to estimate the prevalence of posttraumatic stress disorder (PTSD) among the offspring of genocide survivors and examine study-level moderators influencing PTSD rates across cultural settings. Following PRISMA guidelines, seven peer-reviewed studies were identified through systematic searches of major databases, covering genocides in Rwanda, Cambodia, Armenia and Israel (Holocaust). A total of 1,569 participants were included. Data were extracted on sample size, mean age, gender composition, generation, diagnostic assessment tools, and World Bank country classification. A random-effects model was used to estimate pooled prevalence, and meta-regressions assessed the moderating effects of gender composition and mean age. Heterogeneity was evaluated using I² and Q statistics. The pooled probable PTSD prevalence across the seven studies was 17.9% (95% CI: 9.9%-25.8%), which is significantly higher than global population norms during peacetime and not substantially lower than prevalence estimates reported in civilian populations living in war zones. Heterogeneity was substantial (I² = 95.03%, p <.001). Meta-regressions found no significant moderating effect of gender composition or age, possibly due to the limited number of studies with complete data and variations in study methodology. Overall, these findings underscore the persistent impact of genocidal trauma, highlighting how its effects extend beyond directly exposed individuals to shape the mental health of subsequent generations.
