Potential risk factors can have a high relative risk but be statistically not-significant or vice versa, depending largely on sample size. Therefore, it is important to always consider high relative risk values (say >3) as being worth further investigation, even if they are not statistically significant. This is particularly true when the estimate is based on a small total count of animals (small sample size).
