*Higher-risk papillary disease was defined as HG/Grade 3 T1, or multiple and recurrent and large tumors (diameter ≥3 cm).
†PD-L1 status was determined by the percentage of tumor cells with any membrane staining above background or by the percentage of tumor-associated immune cells with staining at any intensity above background; ICP represents the percentage of tumor area occupied by any tumor-associated immune cells; IC+ represents the percentage area of ICP showing PD-L1–positive immune cell staining. PD-L1 status was considered high if any of the following criteria were met: ≥25% of tumor cells showed membrane staining; or ICP was >1% and IC+ was ≥25%; or ICP was 1% and IC+ was 100%.
The DFS prespecified patient subgroup analysis was not powered to show differences between or within individual subgroups and was not powered for statistical significance.
