In a report by Reuters, the headline read Emotional Support Helps Breast Cancer Survival The headline was based on a study of 847 women (442 black women and 405 white women) with breast cancer and how they fared over a 9-year period. The authors wrote Women in our study who reported low levels of both emotional expression and emotional support experienced 2 to 4 times greater breast cancer mortality than women reporting high levels of both. Is a conclusion that more emotional support causes a reduction in breast cancer mortality justified?
a. Yes, because the study was a randomized study.
b. Yes, because there were women who had a lot of emotional support as well as women who did not.
c. No, because the study was a retrospective study.
d. No, because the study was an observational study.
