Relative risk with 95% confidence intervals
Relative risk is calculated in prospective studies
If relative risk and the confidence interval crosses over 1.0, meaning that the event is just as likely to occur as not occur, then researchers have a non-significant association between the variables.
If relative risk and the confidence interval are both entirely above 1.0, then people are MORE AT RISK of developing the outcome as a result of the treatment or exposure.
If relative risk and the confidence interval are both entirely below 1.0, then people are LESS AT RISK of developing the outcome as a result of treatment or exposure, denoting a "protective" effect.
