You test whether HIV status (positive vs. negative) is associated with getting non-Hodgkin's lymphoma (positive vs. negative) later in life. You perform a logistic regression and get an OR of 4.70. This can be interpreted as... You test whether HIV status (positive vs. negative) is associated with getting non-Hodgkin's lymphoma (positive vs. negative) later in life. You perform a logistic regression and get an OR of 4.70. This can be interpreted as... The odds of getting HIV in non-Hodgkin's lymphoma patients is 4.70 times the odds of getting HIV in persons without non-Hodgkin's lymphoma. Both of these are true. The odds of getting non-Hodgkin's lymphoma if HIV-positive is 4.70 times the odds of getting non-Hodgkin's lymphoma if HIV-negative
