, In a case-control study, it is found that 20% of the cases have the exposure of interest as opposed to 15% of the controls. It is known from previous methodologi- cal work that the classification for exposure is subject to some error, which is nondifferential and independent with respect to case-control status. It is thought that the sensitivity is somewhere between 60% and 75% and that the specificity is somewhere between 90% and 95%. Calculate improved estimates of the odds ratio using this information on the accuracy of the exposure classification.

An epidemiologist recruits 250 people for a cohort study. Of these potential study subjects, 11 are prevalent cases. The remaining study subjects are followed for 5 years, during which time 21 individuals develop the disease being studied.What is the prevalence of disease at the start of the study Assume all of the cases are still around at the end of the study. What is the prevalence now and What is the incidence proportion over the period of observation?
State for each of the following statements if they are true or false: a. Cumulative incidence ratio, incidence rate ratio and prevalence are always unitless. b. For a given exposure and outcome, if the incidence rate ratio is < 1, then the incidence rate difference is < 0. c. An odds of 2:3 has the same magnitude as a risk of 2/5. d. In a case-control study comparing the association of a specific exposure between cases and controls, the only measure of association that we can directly calculate is the odds ratio. e. Attributable risk is more informative to policymaking than cumulative incidence ratio. Please answer asap and type your answer and do not copy from anywhere please
