Association between PD-L1 expression and (A1) tumor stage; (B1) tumor stage; (C) intravesical therapy of BCG; (D1) tumor grade; (E1) sex; (F1) smoking history; (G1) prior use of chemotherapy; (H1) lymph node metastases; and (I1) distant metastases in bladder cancer. Association between PD-L1 expression and (A2) tumor stage; (B2) tumor stage; (D2) tumor grade; (E2) sex; (F2) smoking history; (G2) prior use of chemotherapy; (H2) lymph node metastases; (I2) distant metastases; (J) recurrence; (K) death due to UTUC for patients with UTUC. Figure 2(A, C–K) expression of PD-L1 was defined by tumor cells. Figure 2(B) expression of PD-L1 was defined by tumor-infiltrating immune cells.

Abbreviations: PD-L1, programmed cell death-1; BCG, bacilli Calmette-Guerin; UTUC, upper urinary tract urothelial carcinoma; OR, odds ratio.
