1. Which of the following is true about an observational prospective cohort study being designed to study the association
between cigarette smoking (smoking 1 pack of cigarettes per day, smoking <1 pack of cigarettes per day, or no
smoking) to be assessed on 3/1/19, and catching a cold between 3/2/19 and 3/31/19?
This design minimizes the potential for systematic differences between the exposure groups.
Both the exposure and outcome are measured at the same point in time.
Subjects self-select to be in the exposure groups, so potential confounders will need to be considered when
assessing the outcome/exposure relationship.
This design ensures that that smoking increases the chances of getting a cold in March of 2019.
