- Calculate the risk ratio for DVT among exposed and unexposed women. (2 points)
Homework Answers
Hey, welcome to Chegg. I hope my answer will be of some help to you. Thank you!
The probability of DVT in exposed (OCP using) women = Number of DVT cases/ Number of exposed participants
= 90/ 6600 = 0.01363
The probability of DVT in unexposed ( Non-OCP using) women = Number of DVT cases/ Number of unexposed participants
= 40/ 3800 = 0.01052
Risk Ratio can calculated by the ratio of probability of DVT in exposed participants to the probability of DVT in unexposed participants.
RR = (0.01363) ÷ (0.01052) = 1.29

Q: Compare the assumptions of physician-centered and
collaborative communication. How is the caregiver’s role different
in each model? How is the patient’s role different?
Answer: Physical-centered communication involves the specialists
taking control of the conversation. They decide on the topics of
discussion and when to end the process. The patient responds to the
issues raised by the caregiver and acts accordingly. On the other
hand, Collaborative communication involves a...

Please read the article and answer about questions. You and the Law Business and law are inseparable. For B-Money, the two predictably merged when he was negotiat- ing a deal for his tracks. At other times, the merger is unpredictable, like when your business faces an unexpected auto accident, product recall, or government regulation change. In either type of situation, when business owners know the law, they can better protect themselves and sometimes even avoid the problems completely. This chapter...
