When you calculate a risk ratio using a contingency table you get a point estimate. This risk ratio point estimate represents the association in your specific data. Once we run statistical tests, we can identify if this risk ratio is significant or not in the context of a larger population by looking at the the 95% confidence interval or p-value. If the risk ratio for my study was 0.64, which confidence interval would suggest significance and which would suggest non-significant results? - Not significant - Significant (0.33 - 0.95) (0.44 - 1.56)
