Clinical characteristics between the two groups were comparable. Abnormal BET was observed in 53% of patients. Rates of abnormal breath tests were comparable among patients with or without abnormal BET. Patients with positive vs. negative breath tests had similar anorectal pressures, rectal sensory function, and BET results. There were significantly more negative breath tests in GBT (64%) versus LBT (35%), with higher rates of small intestinal bacterial overgrowth (SIBO) in LBT versus GBT (SIBO only: 20.1% vs. 7.6%; SIBO+IMO: 21.5% vs. 5.5%;\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions and Inferences<\/jats:title>\n                    <jats:p>The presence of evacuation dysfunction does not impact the results of the breath test.
