Mapping the Symptom Networks of Depression, Anxiety, and Their Comorbidity Among Chinese Individuals Under Community Correction.
Article in Psychiatry investigation, 2026. 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
objectiveIndividuals under community correction are a high-risk population for anxiety and depression, which frequently co-occur. However, the symptom network structures of anxiety, depression, and their comorbidity in this population remained unexplored. This study addresses this gap using a network analysis approach.
methodsA total of 818 Chinese individuals under community correction (134 females, 684 males; over 95% aged 18-60 years) completed the Self-Rating Anxiety Scale (SAS) and Self-Rating Depression Scale (SDS). Separate symptom networks for anxiety and depression were estimated to identify central symptoms using expected influence (EI), while a comorbidity network was estimated to identify bridge symptoms using bridge EI and bridge betweenness. Directed acyclic graph (DAG) analyses were then conducted to identify potential trigger symptoms and further clarify the roles of central and bridge symptoms.
resultsA total of 36.7% and 13.1% of participants reported depression and anxiety symptoms, respectively, with 11.0% exhibiting comorbidity. In the anxiety network, "panic" (SAS-03) was the central symptom (highest EI) and the key trigger symptom in the DAG. In the depression network, "emptiness" (SDS-18) was the central symptom, while "fatigue" (SDS-10) was the key trigger. In the comorbidity network, "insomnia" (SAS-19), "sleep disturbance" (SDS-04), and "fatigue" were identified as bridge symptoms. In the comorbidity DAG, "fatigue" acted as a key trigger, facilitating the transmission from depression to anxiety via "sleep disturbance" and "insomnia."
conclusionThe study preliminarily examined the phenomenon and mechanisms of anxiety, depression, and their comorbidity among individuals under community correction, providing new insights for intervention planning.
