Classification of Depressive Symptoms Among Bereaved Families of Sewol Ferry Disaster Victims Using Latent Profile Analysis.
Article in Psychiatry investigation, 2025. 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
objectiveAfter the Sewol Ferry Disaster, most empirical studies on the bereaved families of victims conceptually categorized their depressive symptoms. However, the actual depressive features of bereaved families and the factors that influence such features remain unclear. Accordingly, this study aimed to categorize latent types of depression using latent profile analysis based on the sub-variables of the Patient Health Questionnaire-9 and identify the influencing factors for each type.
methodsThis study included 302 individuals aged ≥15 years who were members of the bereaved families of Sewol Ferry Disaster victims. Data were collected through an online questionnaire survey platform between October 5 and December 13, 2021.
resultsLatent profiles were divided into three groups: "overall low-level" (LOW), "lethargy and physical symptoms" (LPS), and "overall high-level" (HIGH). The participants with lower levels of social support and higher levels of family relationship stress were more likely to belong to the HIGH than LPS group. Moreover, the participants with higher levels of non-family relationship stress were more likely to belong to the LPS than the LOW group. Furthermore, the participants with poorer physical health and lower levels of social support were more likely to belong to the HIGH than LOW group.
conclusionSince bereaved families with poorer physical symptoms showed a higher risk for depressive symptoms, strategies to prevent their physical health problems are needed to ensure that their depressive symptoms do not become worse in the future.
