Multivariate logistic regression model for predictors of length of stay (LOS) in patients hospitalized with acute coronary syndrome and concomitant gastrointestinal bleeding. Performing gastrointestinal endoscopy was included along with other variables and comorbidities that can affect LOS. LOS: length of stay; GIE: Gastrointestinal endoscopy; DM: Diabetes mellitus; CHF: Congestive heart failure.
