Predictive Role of Red Cell Distribution Width in Upper GI Bleeding Patients
Efficacy of Red Cell Distribution Width as a Predictor of High Risk and Early Mortality in Upper Gastro-intestinal Bleeding
研究概览
详细说明
This is a retrospective clinical study including the UGI patients in ED. All data will be collected through the electrical medical records. The major endpoints are the high risk patients and 30-days mortality which defined cases of including any of one among the death, re-bleeding, and received the intervention (such as blood transfusion, endoscopic therapy and operation).
Investigators assessed the relationship between initial RDW level and high risk patients and 30-days mortality. In addition, investigators compare the dicrimination power for predicting outcomes between the UGIB scoring system and RDW level.
Univariate and multivariate logistic regression testing and a Cox hazard regression model were used to determine the factors associated with outcome variables. In addition, investigators constructed receiver operating characteristic curves, and the areas under the curves and confidence intervals were calculated to compare the discriminatory power for outcomes.
