Overall survival (OS) of untreated patients vs treated patients with non‐metastatic muscle‐invasive bladder cancer (MIBC), matched on age, body mass index, renal function, performance status, tumour stage, and previous radiation in abdomen/pelvic area (A), with patients who deceased within 90 days after diagnosis excluded (B), and stratified by age (C). Median OS of treated patients aged ≥75 years: 13.9 months (95% CI 12.3–17.5). Median OS of treated patients aged <75 years: 22.8 months (95% CI 18.3–26.0). Log‐rank P = 0.007. Median OS of untreated patients aged ≥75 years: 6.2 months (95% CI 5.1–7.4). Median OS of untreated patients aged <75 years: 6.5 months (95% CI 3.4–9.5). Log‐rank P = 0.908.
