Exploring the role of impulsivity, aggression, lipid profiles, and inflammatory markers in suicide attempts: a crossdiagnostic study.

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
objectiveThis study aimed to explore the relationship between suicidal behavior and various factors, including peripheral inflammatory markers, atherogenic indices, serum albumin levels, impulsivity, and aggression.
methodsThis cross-sectional study included 100 patients hospitalized for a recent suicide attempt, 74 individuals with psychiatric disorders without a recent suicide attempt, and 85 healthy controls (HC). Peripheral inflammatory markers, atherogenic indices, and serum albumin levels were assessed using fasting blood samples. Impulsivity and aggression were measured with the Barratt Impulsiveness Scale-11 (BIS-11) and the Buss-Perry Aggression Questionnaire (BPAQ).
resultsSerum albumin levels were significantly lower (p = 0.001), and the neutrophil-to-albumin ratio (NAR) was significantly higher (p < 0.001) in individuals who had recently attempted suicide, compared to both individuals with psychiatric disorders without a recent suicide attempt and the HC group. Logistic regression identified NAR (p = 0.001), low albumin levels (p = 0.017), impulsivity (p = 0.001), and aggression (p < 0.001) as significant predictors of suicidal behavior. Lower education (p = 0.001) and lifetime substance use disorders (p = 0.003) were also significant predictors. No significant differences were found in atherogenic indices.
conclusionLow albumin levels and increased NAR are key predictors of suicide risk, underscoring the role of inflammation. Additionally, addressing educational disparities and substance use is crucial for suicide prevention strategies.
