Sankey diagrams connecting the initial diagnosis of NMIBC and subsequent pathological pathways according to the use of photodynamic diagnosis. Of 990 patients (495 per group), 155 in the WL‐PDD‐TURBT group (upper panel) and 81 in the PDD‐TURBT group (lower panel) had at least one instance of bladder recurrence and/or progression. Each vertical bar represents a pathological category: Ta low‐grade (LG), Ta high‐grade (HG), isolated Tis, and T1 HG. The height of the bars is proportional to the number of patients. TURBT, transurethral resection of bladder tumour; WL, conventional white‐light; PDD, photodynamic diagnosis‐assisted; NMIBC, non‐muscle‐invasive bladder cancer; UC, urothelial carcinoma
