Summary
South Korea faces a high suicide rate, with intentional intoxication being a common method. This study identified key risk factors like alcohol consumption, psychiatric disease, and male sex to help target prevention efforts.
Area of Science:
- Public Health
- Emergency Medicine
- Psychiatry
Background:
- South Korea experiences a high and increasing suicide rate.
- Intentional intoxication is a prevalent method for suicide attempts and a frequent reason for emergency department visits.
Purpose of the Study:
- To identify predictors of suicide risk specifically among individuals attempting suicide via intentional intoxication.
- To utilize decision tree modeling for risk factor identification in intentional intoxication cases.
Main Methods:
- Retrospective analysis of a 4-year hospital registry (2013-2016) involving 4,023 patients presenting with intoxication.
- Data collected included demographic factors (sex, age, smoking, alcohol consumption, psychiatric disease), therapeutic adherence, physical disease, and toxicological factors.
- Decision tree modeling was employed, followed by multiple logistic regression analysis to identify significant risk factors.
Main Results:
- Intentional intoxication accounted for 55.9% (2,247) of all intoxication cases.
- Decision tree analysis identified alcohol consumption, old age, psychiatric disease, smoking, and male sex as significant predictors.
- Multiple logistic regression confirmed these predictors and additionally highlighted poor therapeutic adherence and physical disease.
Conclusions:
- Key predictors for suicide risk via intentional intoxication have been identified.
- Decision tree modeling offers an effective, specific, and realistic approach to identifying at-risk populations for targeted suicide prevention strategies.

The “tree of life” describes the evolution of life and the evolutionary relationships between organisms. The root of the tree is the common ancestor to all life on Earth. All other species radiate from this point, much like the branches of a tree. The numerous tips of these branches on the tree of life represent every living, or extant, species. Extinct species, which are species that no longer exist, can be found towards the center of the tree. Currently, these organisms, both...

01:19Survival Tree
429
Survival trees are a non-parametric method used in survival analysis to model the relationship between a set of covariates and the time until an event of interest occurs, often referred to as the "time-to-event" or "survival time." This method is particularly useful when dealing with censored data, where the event has not occurred for some individuals by the end of the study period, or when the exact time of the event is unknown.

Phylogenetic trees come in many forms. It matters in which sequence the organisms are arranged from the bottom to the top of the tree, but the branches can rotate at their nodes without altering the information. The lines connecting individual nodes can be straight, angled, or even curved.

The human bronchi and bronchial tree play a crucial role in the respiratory system, facilitating the exchange of oxygen and carbon dioxide. Let's delve into the intricate structure and functions of these respiratory components.
The trachea, commonly known as the windpipe, is a tube that connects the larynx (voice box) to the bronchi. At a point called the carina, it bifurcates into two primary bronchi. The right primary bronchus is wider, shorter, and more vertical than the left primary...

Decision-making is a fundamental cognitive process that involves evaluating alternatives and selecting among them. This process can range from simple choices, such as deciding what to wear, to complex decisions, like choosing a major in college or a career path. The complexity of the decision often dictates the approach we use, which can be broadly categorized into two types: automatic and controlled decision-making.
Automatic decision-making is fast, intuitive, and relies on gut feelings...

The process of hypothesis testing based on the P-value method includes calculating the P- value using the sample data and interpreting it.
First, a specific claim about the population parameter is proposed. The claim is based on the research question and is stated in a simple form. Further, an opposing statement to the claim is also stated. These statements can act as null and alternative hypotheses: a null hypothesis would be a neutral statement while the alternative hypothesis can...
