Think back to the example study earlier in this lecture. The researchers followed 3 participants in a 5 year study. You have already calculated the total person-time and found out that it is 10 years. During the study, there was one case of the disease. Calculate the rate. 101.13.33

The researchers followed 3 participants in a 5 year study. Begin by calculating the person-time for each participant. Then, calculate the total person-time by adding up the three individual person-times. If you find it helpful, you might want to create a graph to help visualize this information. What is the total person-time in this study?Participant 1: Year 1: follow-up, Year 2: lost to follow-up at the end of the yearParticipant 2: Year 1: follow-up, Year 2: follow-up, Year 3: follow-up, Year 4: disease at the end of the yearParticipant 3: Year 1: no observation, Year 2: follow-up, Year 3: follow-up, Year 4: follow-up, Year 5: death at the end of the year10 years 8 years 7 years 15 years

True or False: The formula for a rate is the number of existing cases of the disease outcome divided by the number of people studied, with a mention of the time period under observation.1 pointFalseTrue

Fill in the blanks: ___ ___ are calculated by counting the number of deaths in one year from any given cause in comparison to that of previous/subsequent years, whereas ___ ___ count how many people within a given population suffer from a particular problem.Question 4Answera.Morbidity rates; mortality ratesb.Mortality rates; morbidity ratesc.Health outcomes; disease ratesd.none of the above

Last year, a city with a population of 500,000 had 50,000 individuals diagnosed with diabetes. This year, 1000 more people were diagnosed. Assuming no changes in population size, what is the incidence rate of diabetes in this population? Group of answer choices 0.102% 20% 10.2% 0.2%

The spread of a disease can be modeled as , where N is the number of infected people, and t is time (in days).How long will it take until the number of infected people reaches 1,400?
