Table 2

ORs (95% CIs) for all-cause mortality across groups of RDW.

OR: odds ratio; CI: confidence interval.
Models were derived from logistic regression.
Adjust I model adjust for: age, ethnicity, and gender.
Adjust II model adjust for: age, ethnicity and gender, liver disease, stroke, SAPSII, SOFA, anion gap, bicarbonate, creatinine, hemoglobin, glucose, CAD, platelet, CHF, and atrial fibrillation.
