Fig. 3From: Impact of tissue sampling on accuracy of Ki67 immunohistochemistry evaluation in breast cancerError results as function of tissue area evaluated. The resampling procedure was simulated for each individual tumor case using 50,000 iterations for each count of hexagons (HexN). Analysis results are split by tumor heterogeneity level. Error measurement (Coefficient of error) is expressed by mean of all casesBack to article page
