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
objectiveThis study aimed to identify different symptom profiles of complicated grief/bereavement-related posttraumatic stress disorder (PTSD) and examine the associations with social life factors, posttraumatic growth, and quality of life in a sample of parents whose children died in Sewol ferry accident.
methodsA total of 272 bereaved parents affected by the Sewol ferry accident participated and completed self-report scales about traumatic loss-related symptoms. The latent profile analysis (LPA) of complicated grief and posttraumatic symptoms was classified. To examine the predictors (interpersonal stress/familial conflict/social support) and outcomes (posttraumatic growth/quality of life) of the traumatic loss symptom profiles, an automatic three-step approach was chosen.
resultsThe LPA identified three symptom profiles of complicated grief and posttraumatic stress: low symptomatology group (30.4%), moderate symptomatology group (49.6%), and high symptomatology group (20.0%). Higher perceived interpersonal stress significantly increased the odds of moderate and high symptomatology, while higher family stress was a significant predictor for high symptomatology compared to both low and moderate symptomatology groups. In addition, higher perceived social support significantly decreased the odds of being in both moderate and high symptomatology groups compared to the low group. The low symptomatology group showed the highest quality of life, followed by the moderate and high groups. Posttraumatic growth was also significantly different between the classes, with the moderate symptomatology group reporting higher growth than the low symptomatology group.
conclusionOur findings suggest that managing the mental health of people who have experienced a traumatic loss will be a critical component of their quality of life in the future. In addition, interventions to help reduce family conflict and interpersonal stress may be necessary to reduce difficulties associated with psychopathology.
