Median values for rop3 and rop6 were set at 5, the smallest value significantly different from 0 (95% confidence interval). This was due to overall low MPSS values for these genes in the experimental samples. The actual median for rop3 was 2; for rop6, 4. All values in this table are significantly different from the median, with a greater than 99.9% confidence interval.
