The finding that indexes of nutrition status (Alb and TP), indexes related to anemia (e.g., bleeding or iron deficiency) (MCV and MCHC), indexes of clinical activity (LI and pMayo score), and indexes of inflammation or concomitant infection (WBC and CRP) are included as predictors may support our clinical experience that UST is effective for patients with moderate UC rather than severe UC, or that patients with a better general condition tend to be more responsive to treatment. Here, ALB is linked to nutritional disorder.
