Discussion: Cox Proportional Hazards Regression Analysis Custom Essay

Cox Proportional Hazards Regression Analysis
The Cox proportional hazards model is a form of survival analysis that allows you to evaluate the risk of disease during a given period of time. Traditionally, it was used to compare treatments for cancer based

on the length of time of remission following each treatment. Recently, its use has been expanded and it has gained popularity among researchers in public health. For this week’s Discussion, you will consider the

use of the Cox proportional hazards model in a peer-reviewed journal.
Articles: Choose one article from the following list of peer-reviewed journal articles that use Cox proportional hazards regression analysis as the primary methodology.

Then post a brief description of the article that includes the time-to-event variable evaluated and the independent variables that were included in the model. Then, explain what the authors concluded about the

relationship of the independent variables and the time-to-event variable (include discussion of the hazards ratio). Finally, explain why you think the researchers chose survival analysis to evaluate this

relationship.
