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: Post-traumatic stress disorder (PTSD) is common among trauma-exposed older adults but often under-recognized. Network analysis conceptualizes PTSD as a system of interacting symptoms and identifies the symptoms most central within the network. Evidence from older adults in Vietnam is scarce. Objective: To estimate the PTSD symptom network and identify the most central symptoms in trauma-exposed older Vietnamese adults. Methods: Cross-sectional data came from the second wave (2021-2022) of the Vietnam Health and Aging Study. From 301 community-dwelling adults aged ≥60 years, the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) PTSD symptom network was estimated in the 90 participants with complete symptom data. PTSD symptoms were assessed with the Vietnamese-validated PTSD Checklist for DSM-5 (PCL-5). A regularized partial-correlation network (EBICglasso) was estimated from polychoric correlations. Node centrality was quantified using Expected Influence (EI), and stability was assessed using a case-dropping bootstrap. Results: The network comprised 19 of 20 PCL-5 nodes (D7 unavailable). Persistent negative emotional states (D4; EI = 1.306) and avoidance of trauma-related thoughts or feelings (C1; EI = 1.196) were the most central nodes, followed by psychological cue reactivity (B4; EI = 1.154). Sleep disturbance (E6; EI = 0.664) and physiological cue reactivity (B5; EI = 0.722) were comparatively peripheral. The ranking of the most central nodes was reproducible under the case-dropping bootstrap. Conclusion: In older Vietnamese adults with lifetime war trauma, cognitive avoidance and persistent negative affect were the most central PTSD symptoms. Because the design was cross-sectional and the rural sample may not be representative, these findings are associational and cannot establish symptom causation or treatment priority. Trauma-focused approaches, including Prolonged Exposure and Cognitive Behavioral Therapy, warrant further evaluation.
