Learn how to develop a web of causation to identify confounders.
- [Instructor] Welcome to Chapter Two, Section Five.…Where we work some more with confounders.…In this section, we will identify confounders…by looking in the literature.…And by making a web of causation.…I'll give brief examples of both.…To identify confounders, we need some practical hypotheses.…We already have selected a sub-population, veterans,…and an exposure, alcohol drinking.…Let's choose two different outcomes so I can demonstrate…two different types of descriptive analyses.…
Sleep duration, which is continuous variable,…and asthma status, which is a binary variable.…So our goal is to identify confounding variables…between our exposure, alcohol drinking,…and our outcomes, which are sleep duration and asthma,…which are not on the causal pathway…between the exposure and the outcome.…And a good way to do that is to go shop…in the scientific literature.…Here is an article from BRFSS about insufficient rest…and sleep among veterans. Let's go to Table 1.…
Here we are. You will see that they have stratified veterans…
This detailed, practical course is designed to help those in the field of public health, medicine, and data science to edit, analyze, and interpret data. Learn how to code new variables, use the forward-stepwise modeling process, and document your decisions. Find out how to visualize results by generating charts and graphics, and how to add tables and figures to your documentation. This course helps equip you to independently design, develop, and execute a full BRFSS analysis, and even publish your results in scientific publications or journals.
