If there is a graph that shows a bunch of patients and its labeled as basically a timelime that shows when someone was diagnosed with a disease, but then it also labels patients who were lost to follow up. When calculating the incidence would you still include the lost to follow ups or simply calculate the incidence as the # of new diseased/whoever is left in the study?
I.e 20 patient time lines, 5 of them were diagnosed with the disease somewhere along the time line and 7 were lost to follow up.
Would incidence be 5/20 or 5/13
