It's a case control study. We have matched sets of cases and controls. Cases have the outcome and controls do not. We look among the research subjects for various exposures and apply statistical calculations to see if cases have/had a certain exposure more frequently than controls (exposure therefore equals a risk factor) or less frequently than controls (exposure therefore equals a protective factor). The statistical measures we use are the odds ratio and the confidence interval.
