Number in data frame = 6931, number in model = 3344, missing = 3587, AIC = 534.7, C‐statistic = 0.982, H&L = chi‐sq(8) 6.30 (p = 0.614).
Abbreviation: CI, confidence interval.
a
OR, adjusted odds ratio; a P‐value, adjusted p‐value.
Multivariable analyses were conducted using logistic regression models utilizing the simultaneous method. The models were adjusted for gender, age, WBC (white blood cells); NEU (neutrophils); HB (heamoglobin); PLT (platelet count).
Percents are row percentages.
