TUMOR
The data regarding downstaging were compared between the Socazolimab + TP and Placebo + TP groups. Patients with T downstaging or N downstaging were selected separately for further comparison. T0, Tis/T1, T2, T3, and T4 were defined as Grades 0, 1, 2, 3, and 4, respectively, and downstaging grades were quantitatively calculated. For example, the T downstaging grade is 3 for a patient whose tumor was evaluated as T3 (i.e., Grade 3) prior to surgery and T0 (i.e., Grade 0) after surgery. The grades of T downstaging in the Socazolimab + TP group and Placebo + TP group were then compared, and statistical analysis was performed.
