Application research on the predictive model for violent behavior in hospitalized patients with severe mental disorders.
Article in World journal of psychiatry, 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
backgroundTo understand the current situation of violent behavior among hospitalized patients with severe mental disorders (SMDs), analyze its influencing factors, establish a predictive model and draw a nomogram, providing screening tools for medical staff to accurately identify SMDs who have violent behavior and the direction of early intervention.
aimTo investigate the determinants of violent actions in hospitalized patients with SMDs.
methodsThis research included 440 inpatients with SMDs who were admitted to the Wutaishan Hospital from January 2025 to June 2025. Data collection and analysis aimed to pinpoint independent contributors linked to aggression in this patient group. An advanced logistic regression analysis with multiple variables was performed using R, followed by the creation of a line chart to display the forecast outcomes of the model.
resultsOf 120 patients exhibited violent behavior (incidence rate = 27.30%). Education level, cigarette smoking, length of hospitalization, age, psychotic symptoms based on the Brief Psychiatric Rating Scale, and C-reactive protein were independent risk factors for violent behavior. Education level and age served as protective elements among the factors analyzed. The receiver operating characteristic curve area for the training and test sets was calculated to be 0.94 and 0.93, respectively. The calibration graph demonstrated that the model was accurately adjusted. The clinical decision curve demonstrated that the model provided significant practical benefits.
conclusionThe predictive mode provided a valuable theoretical basis for ward staff to identify inpatients with SMDs at elevated risk of aggression in the early phase.
