Question 2Which of the following types of events can be measured by a risk and/or a rate? 1 pointNewly developed cases of diseaseRecurrence of a diseaseDevelopment of a drug or treatment side effectAll of the above

What does "population at risk" (PAR) refer to in epidemiological studies?Select one alternative:Members of the population who are capable of developing the disease or condition being studied.Only individuals who have already developed the disease or condition being studied.Members of the population who are actively immune to the disease or condition being studied.Only individuals who are incapable of developing the disease or condition being studied.

Step 1 in the risk management process is:  A. Understand the risk  B. Identify the risk  C. Analyse the risk  D. Rank the risk

True or False: The denominator of a risk is not fixed by the “at-risk” population size at the beginning of a study observation period. 1 pointTrueFalse
