RDW-to-ALB Ratio Is an Independent Predictor for 30-Day All-Cause Mortality in Patients with Acute Ischemic Stroke: A Retrospective Analysis from the MIMIC-IV Database

Table 3

Association between different RAR levels and outcomes among AIS patients in the validation database.

Validation EICU hospital mortality	Nonadjusted model OR; (95% CI) value	Minimally adjusted model OR; (95% CI) value	Fully adjusted model OR; (95% CI) value
RAR			1.2 (1.0, 1.3) 0.010
RAR (three groups)
Q1	1.0	1.0	1.0
Q2	1.1 (0.8, 1.5) 0.384	1.1 (0.8, 1.5) 0.484	1.1 (0.7, 1.7) 0.687
Q3			1.6 (1.1, 2.5) 0.024
for trend			1.3 (1.0, 1.6) 0.016

Nonadjusted model adjusts for the following: no covariates were adjusted for. Minimally adjusted model: we only adjusted for sex, ethnicity, and age. Adjust II model adjusts for the following: sex, ethnicity, age, GCS, hypertension, angina; cardiovascular disease, cirrhosis, COPD, diabetes, stroke, TIA, BUN, anion gap, and WBC. GCS: Glasgow Coma Scale; COPD: chronic obstructive pulmonary disease; TIA: transient ischemia attack; BUN: blood urea nitrogen; WBC: white blood cell.
