Example images of non-invasive urothelial carcinomas of the bladder graded in this study. Case 1, shown at low power (A) and the insert at high power (B), is an example of complete inter-observer agreement of a low grade, grade 2 tumour. There was also complete intra-observer agreement on subsequent grading sessions (glass and digital). Case 43 (C&D) is a high grade, grade 3 tumour with complete intra-observer and inter-observer agreement. Case 44 (E&F), is an example where pathologists B and C both downgraded the tumour from high grade on glass to low grade on digital assessment (pathologist A deemed this case high grade on both media)
