Which one of the following is not a special incidence rate: (A) Attack rate, (B) Secondary attack rate, (C) Hospital admission rate, (D) standardized moality rate
Answer is D. ref: Park's 23rd edition pg 58 All except D are special incidence rate. Standardised moality rate is adjusted moality rate, which removes the confounding effect of different age structures and yields a single standardised or adjusted rate by which moality experience can be directly compared.
