• Background (one page maximum)
• Statistics and information about the health outcome/disease(s)
• Statistics and information about the exposure/risk factor(s)
• Brief discussion of possible connection between exposure(s) and outcome(s) and justification for the study
• Target population and sample size
• Description of target population and sample
o Inclusion and exclusion criteria
