## Figure 2.
Evaluation of the minimum area required for quantitative analyses of CD68, CD3 and
CD20 cells. For each of the tissue markers studied, a plot was generated to show the effects
of increasing sample size (that is, the number of high-power fields examined) and
the proximity of this sample mean from the overall determination of area fraction.
Data represent the mean values of all cases. As the number of high-power fields examined
increases, the difference between the sampling mean and the overall mean reduces.
A threshold value of 10% of the overall mean (arrows) was set as providing a reasonable
estimator of the true sample mean.
