Table 4.
Crosstab of the assessment results of all (inguinal and secondary) LNs, software analysis vs. correction of computer assessment by specialists (a1 = Number of true-positive findings; b1 = Number of false-positive findings; c1 = Number of false-negative finding; d1 = Number of true-negative findings)
| Correction of computer assessment by specialists | ||||
|---|---|---|---|---|
| SLN proven | SLN disproven | Sum | ||
| Software analysis | Positive findings by software | True-positive 127 (a1) |
False-positive 88 (b1) |
all positive findings 215 (a1 + b1) |
| Negative findings by software | False-negative 16 (c1) |
True-negative 572 (d1) |
all negative findings 588 (c1 + d1) |
|
| Sum | all true SLN 143 (a1 + c1) |
all false SLN 660 (b1 + d1) |
all findings 803 (a1 + b1 + c1 + d1) |
