Outcomes were defined using International Classification of Diseases, Ninth Revision (ICD\u20109) and Tenth Revision (ICD\u201010)\u2010codes with manual cross\u2010reference for a hemoglobin drop, transfusion, or hemodynamic compromise to further define CIGB. Of 3873 patients, 2061 (53.2%) received PPIs. CIGB was rare but higher in the PPI group (0.34% vs. 0%, RR\u00a0=\u00a01, 95% CI, 1\u20131;\n                      <jats:italic>p<\/jats:italic>\n                      \u00a0=\u00a00.013); however, substantial group differences existed possibly predisposing the PPI group to CIGB. Hospital mortality was higher in the PPI group (42.1% vs. 29.1%, RR\u00a0=\u00a01.23, 95% CI, 1.17\u20131.29;\n                      <jats:italic>p<\/jats:italic>\n                      \u00a0&lt;\u00a00.0001).
