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
Background: Trauma exposure is linked to increased psychosis risk; however, critical questions remain about how trauma exposure relates to psychotic-like experiences (PLEs), including the overall effect and whether trauma type, number of exposures, and methodological/sample characteristics influence the relationship. Method: A meta-analysis (following PRISMA guidelines) on the relationship between childhood trauma and PLEs was conducted. Effect size by trauma type (emotional abuse, physical abuse, sexual abuse, emotional neglect, physical neglect, bullying, discrimination) and number, assessment methods for trauma and PLEs, and the sex and race/ethnicity compositions of the sample were recorded. Results: 92 studies (104 samples; 171,828 individuals) were included. The mean effect size was Discussion: This meta-analysis highlights the importance of expanding the assessment of trauma, including information about chronicity and about exposures such as bullying and discrimination. Research examining the relationship of these more nuanced measures of trauma exposure and later psychosis risk is critical to inform public health and policy decisions.
