FIGURE 4.

Swimmer plots of patients with IBCG‐defined progression. Of 990 patients (495 per group), 41 in the WL‐TURBT group (left panel) and 15 in the PDD‐TURBT group (right panel) demonstrated IBCG‐defined progression. Swimmer plots before and after the onset of IBCG‐defined progression indicate the adjuvant treatments, treatment‐free duration, sequential treatments, cystectomy‐free duration, and overall survival. TURBT, transurethral resection of bladder tumour; WL, conventional white‐light; PDD, photodynamic diagnosis‐assisted; MIBC, muscle‐invasive bladder cancer; UC, urothelial carcinoma; BCG, bacillus Calmette‐Guerin
