The coefficient of variation (SD/Mean) in percentage of SOX2-positive cells is shown for each patient in the TMA semiquantitative analysis. When the variance is plotted against the mean percent A or the mean raw score B, there is a higher variance in cases with low levels of SOX2 expression. Using the median cut-off of 50% for percent of SOX2-positive cells in the TMA cores, the mean variance is 48% in the low-expressing group and 26.6% in the high-expressing group (p < 0.0005)
