  • Q8

    In a cohort study, the risk ratio of developing diabetes was 0.86 when comparing consumers of tea (exposed) to those who did not drink tea (non-exposed). Which one statement is correct ?

    The tea drinkers have lower risk of developing diabetes

    The tea drinkers have higher risk of developing diabetes

    Based on the information given, we cannot tell if the observed difference in disease risk is the result of chance. 

    Risk ratio is close to the value one, so there is no difference in disease risk between the two groups.
