Network analysis of depression, anxiety, and stress symptoms in Brazilian nursing workers.
Article in Revista brasileira de enfermagem, 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
objectivesto explore the network structure of depression, anxiety, and stress symptoms among Brazilian nursing workers.
methodscross-sectional study using nonprobability sampling. Participants were 4,053 nursing workers. Symptoms of depression, anxiety, and stress were assessed using the Depression Anxiety Stress Scales-21. Data were analyzed using psychological network analysis, applying a partial correlation model with LASSO regularization method. Node centrality was assessed using strength, closeness, and betweenness indices.
resultsthe symptoms with the highest strength centrality were "I felt that I was using a lot of nervous energy," "I was unable to become enthusiastic about anything," and "I felt I was close to panic." The symptom "I felt that I was using a lot of nervous energy" showed the highest closeness and betweenness indices.
conclusionsthe identified central symptoms may play a structuring role in the activation of other symptoms and may help guide strategies to prevent and manage psychological distress among nursing workers.
