Number of ultrasound-guided biopsy sections required for quantitative analysis. Evaluation of the number of ultrasound-guided biopsy sections required for quantitative
analyses of CD68, CD3 and CD20 cells. Reduction in the percentage mean difference
can be obtained by studying 2.5 mm^{2 }from an increasing number of sections. Arrows, number of sections that allow one to
achieve a percentage mean difference lower than 10%. x axis, number of sections studied; y axis, percentage mean difference.
