: Professor Sue Mallett, a Professor of Diagnostic and Prognostic Medical Statistics at University College London, and Busola Adebusoye, a statistician and postdoctoral researcher at University College London, provided statistical advice for this manuscript.
: Written informed consent was not required because the study used anonymised clinical records and magnetic resonance imaging scans collected during routine care and service evaluation, with no impact on patient management.
: Institutional Review Board or Research Ethics Committee approval was not required because clinical records and magnetic resonance imaging scans were routinely reviewed as part of an audit performed for service evaluation of the active surveillance programme at each centre.
: Some study subjects have been previously reported in publications describing the University College London Hospitals and San Raffaele Hospital active surveillance cohorts.
