A researcher studied women with breast cancer to better understand the association between self-rated health and all-cause mortality (Prehn, 1996). Women were interviewed twice, and survival models were used to assess the association between self-rated health 12 months after breast cancer diagnosis and all-cause mortality. The following results were obtained from three different models:
1) State in words the meaning of the odds ratios for self-rated health in model 2. Be sure to include information on statistical significance.
2) State in words the meaning of the odds ratios for self-rated health in model 3. Discuss what these models show about the role of confounding in the self-rated health/mortality association. Justify your response and state your overall conclusions based on the analyses
