Background:

Linear regression is a common statistical method in medical literature.
A review of 36 articles from 1978-1979 revealed its application in data summarization and correlation analysis.

Purpose of the Study:

To analyze the application of linear regression in medical research.
To emphasize the importance of residual plots and confidence bounds in regression analysis.

Main Methods:

Review of 36 original articles published in the Journal in 1978 and 1979.
Analysis of the usage of linear regression for data summarization and correlation calculation.

Main Results:

Linear regression was used to summarize data in 12 out of 36 articles.

Related Experiment Videos

Correlation between two variables was calculated using linear regression in 21 out of 36 articles.
