## Question:

(a) What was the study design and what are the advantages of using this design?

(b) Compute the crude incidence rates of diabetes among women

(c) Table 2 presents the adjusted relative risk of type II diabetes according to quintiles of Total Grain consumption (first 5 lines) relative to the 1st quintile (the lowest consumption as a reference). Calculate the unadjusted (crude, quintile –specific) incidence rate and the crude relative risk (RR) of each quintile in comparison to the first quintile. Comment in your own words whether any pattern of association can be observed from the unadjusted crude RR

(d) In Table 2 model 2 (multivariables  adjustment) of Whole Grain showed the RR of each quintile (increased consumption) relative to the lowest 1st.

What is the pattern of the association?

(e) Why the authors adjusted their analysis for physical activity, smoking alcohol intake and family history. You need to back up your argument with evidence from the data presented in Table 1.

(f) What is the main possible bias in this study? Provide arguments for your answer and how it will affect the estimates.

1. b) Calculate the odds ratio of exposure to child abuse and risk of mental illness and explain in words the meaning of what you found
2. c) What can possibly biases this estimate, explain how it will affect our measure of association- try to think of more than one possibility
