1. Based on the data presented in Figure 1, comment on how the prevalence of uncontrolled asthma differs across anxiety levels. Then,calculate and interpret the crude prevalence ratio for the association of anxiety levels (4^th quartile vs. 1^st quartile) and uncontrolled asthma.
2. How does the prevalence ratio you calculated abovediffer from the odds ratio (OR) found in the article: "Participants with high anxiety were twice as likely to have uncontrolled asthma compared with counterparts reporting low levels of anxiety (odds ratio, 2.00; 95% confidence interval [CI], 1.45-2.74)." What was thepurpose of conducting the adjusted analyses? What variables were considered to estimate the adjusted odds ratio? Interpret the ORsfor the association of anxiety quartiles with uncontrolled asthma. Interpret the dose-response association presented in the paragraph.
