Correlation between iRENEX certainty factors and the median certainty factors of the three human experts regarding obstruction of the left kidney; comparable results (not shown) were obtained for the right kidney. The red lines mark the equivocal boundaries for certainty factors between −0.2 and +0.2. Note the excellent degree of correlation confirming that the conclusions reached by iRENEX have a degree of certainty comparable to those reached by experts (68, reproduced by permission).
