Table 3.

Reduction in cystoscopies and number of recurrences that would be detected using various thresholds from a model using only age and gender, or using age, gender and NMP22 level. Numbers are given per 1000 men with negative cytology.

No. cystoscopies No. recurrences
Performed Avoided (%) Found Missed
Cytoscopy all 1000 (100%) - 261 (100%) -
Cytoscopy those with > 10% risk of recurrence
 Model using age and gender alone 989 11 (1%) 260 1 (0%)
 Model using age, gender and NMP22 923 77 (8%) 257 4 (2%)
Cytoscopy those with >15% risk of recurrence
 Model using age and gender alone 925 75 (8%) 256 5 (2%)
 Model using age, gender and NMP22 771 229 (23%) 236 25 (10%)
Cytoscopy those with >20% risk of recurrence
 Model using age and gender alone 811 189 (19%) 229 32 (12%)
 Model using age, gender and NMP22 582 418 (42%) 202 59 (23%)
