Causality in Epidemiology

Causality in Epidemiology

Causality or causation is a fundamental concept in epidemiology, vital for understanding the relationships between various factors and health outcomes. Despite its importance, there's no single, universally accepted definition of causality within the discipline. Drawing from a systematic review, causality in epidemiology encompasses several definitions, including production, necessary and sufficient, sufficient-component, counterfactual, and probabilistic models. Each has its strengths and...

Criteria for Causality: Bradford Hill Criteria - II

Criteria for Causality: Bradford Hill Criteria - II

The Bradford Hill criteria serve as guidelines for establishing causative links in epidemiological research. Beyond Strength, Consistency, Specificity, and Temporality, key criteria also include Biological Gradient, Plausibility, Coherence, Experiment, and Analogy. These principles assist scientists in assessing the likelihood of causation in complex biological contexts. Below is a summary of these concepts:

Correlation and Causation

Correlation and Causation

Statistical tests can calculate whether there is a relationship, or correlation, between independent and dependent variables. An indirect relationship of the variables signifies a correlation, while a direct relationship shows causation. If it is determined that no connection exists between the variables, then the correlation is a coincidence.
Correlation versus Causation
If the dependent variable increases or decreases when the independent variable increases, there is a positive or negative...

Criteria for Causality: Bradford Hill Criteria - I

Criteria for Causality: Bradford Hill Criteria - I

The Bradford Hill criteria are a group of principles that provide a framework to determine a causal relationship between a specific factor and a disease. There are nine criteria that are pivotal in assessing causality in epidemiological studies. Here's a closer look at Strength, Consistency, Specificity, and Temporality criteria with definitions and examples:

Cause and Effect

Cause and Effect

While variables are sometimes correlated because one does cause the other, it could also be that some other factor, a confounding variable, is actually causing the systematic movement in our variables of interest. For instance, as sales in ice cream increase, so does the overall rate of crime. Is it possible that indulging in your favorite flavor of ice cream could send you on a crime spree? Or, after committing crime do you think you might decide to treat yourself to a cone?

Time-Series Graph

Time-Series Graph

A time-series graph is a line graph with repeated measurements taken at successive intervals of time. It is also called a time series chart. To construct a time-series graph, one must look at both pieces of a paired data set. The horizontal axis is used to plot the time increments, and the vertical axis is used to plot the values of the variable that one is measuring. By using the axes in this way, each point on the graph will correspond to time and a measured quantity. The points on the graph...

Background:

Granger causality is a widely used concept for inferring causal relationships from time-series data.
However, its theoretical underpinnings and practical application, especially concerning spurious causality and latent variables, require careful consideration.

Purpose of the Study:

To provide a comprehensive review of Granger causality for causal inference in time-series data.
To theoretically justify the concept by relating it to other causality measures.
To outline methods for addressing spurious causality and introduce an accessible algorithm for causal discovery.

Main Methods:

Theoretical review and synthesis of Granger causality.
Discussion of challenges like spurious causality and latent variable identification.
Sketch of a non-technical causal discovery algorithm for time-series data.

Main Results:

The review establishes a theoretical basis for Granger causality.
It identifies potential pitfalls of spurious causality and suggests mitigation strategies.
A novel, accessible algorithm for learning causal time-series structures with latent variables is presented.

Conclusions:

Granger causality offers a valuable framework for time-series causal inference.
Addressing spurious causality and incorporating latent variable models are crucial for robust causal discovery.
The presented algorithm facilitates the adoption of advanced causal inference methods by applied scientists.
