Problem:
You are conducting a study looking at the relationship between the presence of a genetic marker and schizophrenia. Here is a 2x2 contingency table indicating if someone has a genetic marker and the presence (or absence) of schizophrenia. Below are the results of your study. Genetic Marker Schizophrenia 11 25 77 116 Calculate the odds ratio for Schizophrenia for those with the genetic marker compared to those without the genetic marker (round to 2 decimal places). odds ratio= After you finish your study, you realize that some of your research assistants were using an old (and inaccurate) tool for assessment of the genetic marker. This means that among both groups (with and without schizophrenia), 15% of the people you listed as having the genetic marker actually didn't and 15% of those you listed as not having the genetic marker actually did have the genetic marker. non-differential misclassification of disease non-differential misclassification of exposure differential misclassification of exposure differential misclassification of disease Using the previous misclassification, calculate the new odds ratio (round to 2 decimal places). When calculating the number of people in each cell of your new 2X2 round to the nearest whole number
