Logistic Regression - Part D

The biostatistician in the previous question also conducted a polytomous logistic regression model to examine the relationship between screen time and depression severity.

Screen time was collapsed into two categories:

• 0= 6 hours of screen time - reference group
• 1 = > 6 hours of screentime

Depression severity was categorized as:

• 0= Mild Depression - reference group
• 1 = Moderate Depression
• 2 = Severe Depression

The results are shown in the table below:

Parameters	Outcome Group	Odds Ratio	95% CI
> 6 hrs/day vs. 6 hrs/day	Moderate Depression	1.45	1.33-1.56
> 6 hrs/day vs. 6 hrs/day	Severe Depression	1.82	1.75-1.95

Write out the two odds ratio interpretations.
