1 · What the graph read from it

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.

2 · The registry

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

Childhood trauma has been linked to personality pathology, including impairments in personality functioning and maladaptive personality traits. However, studies applying contemporary dimensional models such as the Alternative Model for Personality Disorders (AMPD) remain limited in South Korea. The aim of this study was to examine associations between childhood trauma and personality pathology using the AMPD in 800 South Korean adults. Latent variable structural equation modeling was conducted while controlling for age and gender and allowing covariances among trauma subtypes. Childhood trauma showed significant associations with both impairments in personality functioning (Criterion A) and maladaptive personality trait domains (Criterion B), with stronger associations observed for Criterion B. Compared with the Five-Factor Model, pathological personality traits showed greater sensitivity to childhood trauma. Physical neglect and emotional abuse exhibited the strongest associations across both domains. These findings support the applicability of the AMPD for understanding the impact of childhood trauma in South Korea.
