Assume that an individual in this study population cannot get Oz-itis more than once. Round your answers to the nearest hundredth place. (ie. 0.01) Use the following data: . 587 residents in Emerald City enrolled into this study . The study period was from January 1, 1882, to January 1, 1940 . There were 28 cases of Oz-itis when the study began on January 1, 1882 . There was total of 254 person-years of follow-up . After the study began, there were 33 new cases of Oz-itis during the follow-up period. Using the data above, calculate the incidence density (incidence rate) of Oz-itis. State your answer in unit of 100 person-years. I Show your calculations here: Using the data above, calculate and interpret the cumulative incidence of Oz-itis by the end of follow-up. Cumulative incidence: . Show your calculations here: . Interpretation: Using the data above, calculate and interpret the point prevalence of Oz-itis at the beginning of the study. Point prevalence: Show your calculations here: Interpretation: A sample of 100 middle aged and elderly women was followed prospectively for 10 years in order to study rates of ovarian cancer. All subjects entered the study on January 1, 1990,
