Researchers are interested in the relationship between depression and bacterial vaginosis among expecting mothers enrolled in a case-control study. Suppose the following computerized printout reports a summary table for the relationship.
|
A) Calculate the prevalence of the exposure in the investigation.
B) Calculate the prevalence of the disease in the investigation.
C) Calculate the prevalence odds ratio depicting the relationship between the outcome and the exposure.
Choose the most appropriate option
Option 1 a. 12.5% b. 24.45% c. 3.25 |
||
Option 2 a. 11.9% b. 18.45% c. 4.40 |
||
Option 3 a. 22.6% b. 14.45% c. 5.45 |
A) prevalence of the exposure in the investigation =80/672 =0.119 ~ 11.90%
B) prevalence of the disease in the investigation =(124/672)=0.1845 ~ 18.45%
C) prevalence odds ratio depicting the relationship between the outcome and the exposure
=(35/89)/(45/503)=4.40
