Association between Red Blood Cell Distribution Width and Short-Term Mortality in Patients with Paralytic Intestinal Obstruction: Retrospective Data Analysis Based on the MIMIC-III Database

Figure 2

Association between RDW and 28 day mortality for patients with paralytic intestinal obstruction. Notes: A relationship between them was detected after adjusting for sex, ethnicity, age, SBP, DBP, BUN, WBC, serum glucose, creatinine, serum anion gap, APS III, OASIS, MLODS, congestive heart failure, chronic pulmonary disease, renal failure, and liver disease. A nonlinear relationship was found between RDW and paralytic intestinal obstruction mortality in the curve fitting diagram. The solid line in the middle represents the smooth curve fitting between variables. Imaginary lines represent the 95% of confidence interval from the fit. Abbreviations: RDW: red cell distribution width, BUN: blood urea nitrogen, SBP: systolic blood pressure, DBP: diastolic blood pressure, WBC: white blood cell, APS III: acute physiology score III, OASIS: Oxford acute severity of illness score, MLODS: modified logistic organ dysfunction system.
