Epidemiologyepidemiologyhealth serviceshemostasis
What it foundUpper GI bleeding occurred in 83% of GI complications during PCI hospitalizations with 12.4% in-hospital mortality versus 6.1% for lower GI bleeding (adjusted odds ratio 1.74, 95% CI 1.36-2.23), while UGIB incidence rose from 0.90% to 1.13% over 2016-2022.
ContextNational inpatient sample data (2016-2022) document the epidemiology of gastrointestinal bleeding during percutaneous coronary intervention hospitalizations, with distinct incidence, clinical features, and in-hospital outcomes for upper versus lower bleeding events.

Every paper is compared to the standard governing its question. This one is not: either no standard in the corpus matches it, or the comparison did not hold up on review and was withdrawn rather than published unverified. Both are logged.
