* Univariate analysis was performed by t test with analysis of variance. Multivariable regression analysis was performed to examine the influence of each biological variable on clinical outcomes in a stepwise manner to exclude statistical confounding. All statistical analyses were two-sided. AAL = aleuria aurantia lectin.
