Sociodemographic, Clinical and Genetic Correlates of Aggressive and Auto-Aggressive Behaviour in Alcohol-Dependent Individuals - Preliminary 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
Purpose: Reducing the risk of aggressive behaviour requires preventive measures that depend on our knowledge of predisposing factors. The study's aim was to compare sociodemographic variables, clinical variables and the frequency of gene polymorphisms predisposing to destructive behaviour between subpopulations of individuals with a history of suicidality and/or of aggression, both being treated for alcohol dependence. Patients and Methods: Sixty-nine patients hospitalised for alcohol dependence participated in the study. The sociodemographic, clinical (SADD, BPAQ) and genetic variables were compared between subpopulations of alcohol-dependent patients selected according to type of aggressive behaviour, including a history of suicidal behaviour and control nonalcohol-dependent group. Polymorphisms of MAOA, COMT, DRD2 and DAT1 loci that are known as risk factors of mental dysfunctions were investigated. Results: The subpopulation of patients with suicide attempts had a longer time in education than patients with aggressive and suicidal behaviour (11.9 vs 9.7 years). Patients with suicide attempts and patients with aggression had lower levels of alcohol dependence than patients with comorbid suicide attempts and concomitant aggression. For the MAOA gene lower frequency of the G/G genotype with tendency to statistical significance was observed among patients burdened by suicidal behaviour in comparison to patients with aggression and a significantly higher A/G genotype compared to cases with aggression and controls. In the case of COMT polymorphism, the G/G genotype was reported significantly less often among patients with suicide attempts and comorbid aggression than among patients with control group). Conclusion: Compared to patients with either only suicidal tendencies or aggression, those with comorbid aggression and suicide attempts are characterised by poorer social performance. Genetic variation in MAOA loci may be a risk factor for impulsive behaviour like suicidal behaviour, and especially aggression.
