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
objectiveThe Lebanese people have endured through several disasters, such as the Beirut explosion, coronavirus pandemic, and cholera outbreak. However, volunteers who have tried to overcome such national disasters develop emotional stress after witnessing people's death. This study was conducted to explore whether volunteers' depression or anxiety mediates the relationship between grief response and post-traumatic stress disorder (PTSD) symptoms.
methodsWe conducted an anonymous online survey study and collected responses from 270 volunteers in Lebanon from March 20-26, 2023. Demographic information and responses to the questionnaires, which included the Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder-7 (GAD-7), Post-Traumatic Stress Disorder Checklist for DSM-5 (PCL-5), Public Service Motivation scale (PSM scale), Connor-Davidson Resilience Scale-2, and Prolonged Grief Disorder (PG-13) were collected. Variables were compared between volunteers who did and did not witness people's death. Furthermore, we explored the relationships among variables in volunteers who witnessed people's death (n=72).
resultsAmong 270 participants, 72 (26.67%) witnessed people's death. The regression model demonstrated that scores for PG-13 (β= 0.31, p<0.001), PHQ-9 (β=0.21, p=0.011), and GAD-7 (β=0.44, p<0.001) were predictors of the PCL-5 score. Mediation analysis showed that grief reaction directly influenced PTSD symptoms (Z=6.19, p<0.001), whereas depression (Z=1.99, p=0.047) and anxiety (Z=2.79, p=0.005) individually mediated the relationship between grief reaction and PTSD symptoms.
conclusionOur study helps understand the mediating effects of volunteers' depression or anxiety on the relationship between grief reactions and PTSD symptoms.
