a
Indicates the minimum association that the confounders would have to have with both exposure and outcome to explain away the observed adjusted ORs.
b
Indicates the minimum association that confounders would have to have with both exposure and outcome to move the lower confidence limit to include the null. NA indicates lower confidence limit starts below 1.00.
