Multivariable Cox analyses assessing HRs of endoscopic excision and radical nephroureterectomy for non-muscle invasive UC according to different tumor sites. HR of OS of patients with (A) Tis/Ta-stage UC and (B) T1-stage UC. HR of DSS of patients with (C) Tis/Ta-stage UC and (D) T1-stage UC. Notes: the multivariable Cox regression model was adjusted by sex, race, age at diagnosis, year of diagnosis, ‘rural–urban residence at diagnosis, and median household income. Abbreviations: HR, hazard ratios; UC, urothelial carcinomas; OS, overall survival; DSS, disease-specific survival.
