Homework Answers
Answer: ( B) Most commonly in cross sectional studies.
Prevalence incidence bias occurs when excluding the people who are dead due to diseases and excluding those who have recovered from the disease. It can occur in cross sectional studies. To avoid the prevalence incidence bias, incident cases should be used rather than prevalent cases.

When a new prevention measure for a disease is developed, both the incidence and prevalence of the disease will decrease over the long term. 2) In 2015, a diagnostic code for Asperger’s disease was added to the ICD-10 (a cookbook for medical disease). Prior to 2010, there was no code to assign for the condition and thus, clinicians were inaccurately diagnosing Asperger’s disease cases with “unspecified autism”. To individuals not aware of this coding scheme, it...
