Factors associated with aggressive behavior in patients with schizophrenia: a systematic review and meta-analysis.
Synthesis in BMC psychology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundAggression in schizophrenia poses a severe global public health challenge, adversely impacting patients, families, and society. A comprehensive understanding of its associated factors is important for developing effective interventions.
objectiveThis study aimed to systematically review and meta-analyze the factors associated with aggressive behavior in patients with schizophrenia.
methodsFollowing PRISMA guidelines, systematic literature searches were conducted in 10 databases from 2014 to October 2024. Study quality was assessed using the Newcastle-Ottawa Scale (NOS). A meta-analysis was performed using Python 3.11.7 5.4 to calculate pooled odds ratios (ORs) or standardized mean differences (SMDs) with 95% confidence intervals (CIs). Subgroup and sensitivity analyses were used to evaluate heterogeneity.
resultsTwenty-four studies involving 5,096 patients with schizophrenia (1,766 aggressive, 3,330 non-aggressive) were included. The meta-analysis identified several risk factors for aggression: male gender (OR = 1.18), junior high school education or lower (OR = 1.98), a history of violence (OR = 3.33), abnormal levels of serum inflammatory markers (e.g., FT3, FT4, C-reactive protein), frontal lobe abnormalities, and the presence of psychotic symptoms (e.g., high PANSS scores) (all P < 0.05). Conversely, being married was a protective factor in male-only subgroups (OR = 0.61). Higher serum TT3 levels and higher BPRS scores were also found to be protective (P < 0.05).
conclusionsOur findings clarify the role of various factors in aggression among patients with schizophrenia, providing an evidence base for clinical intervention and treatment. In clinical practice, our findings could effectively reduce aggression risk and promote comprehensive patient assessment and management.
