Comparison of 3D printed prostate models with standard radiological information to aid understanding of the precise location of prostate cancer: A construct validation study - Table 4

(A1) rates (%) of major mistakes (total loss of 10 points) in 135 judgments (9 participants x 3 PCA cases x 5 views to judge/case = 135) sub-classified for the five different views in pictures 1–3 of the prostate template (Fig 1) and subdivided for group 1 (Expert urologist) and group 2 (Medical students), and (A2) rates of complete major accuracy (0% major mistakes) out of 27 judgments (9 participants x 3 PCA cases) in the experts and medical students group subdivided for information tool A (Written MRI report), information tool B (3D printed model) and information tool C (MRI presentation in MDT) respectively. (B) minus points (median with IQR) for minor mistakes in the experts und medical students group, sub-classified by (B1) type of minor mistake and by (B2) different views in pictures 1–3 of the prostate template (side (sagittal) view, ventral (coronal) view, transverse (axial) views (ABC)) in information tool A (Written MRI report), information tool B (3D printed model) and information tool C (MRI presentation in MDT).
