NOTE. Missing univariable values for Hispanic ethnicity are caused by an insufficient number of observations in the local survey.
CI, confidence interval; IBD, inflammatory bowel disease; OR, odds ratio.
a
P < .10 on univariable analysis. Only these variables were candidates for multivariable analysis.
b
P < .05 on multivariable analysis.
