Box-plot of methylation indices for each candidate gene analyzed by pyrosequencing.

<p>Genes are ordered by Mann-Whitney <i>p-value (</i>** p-value<0.0001 and * p-value<0.05). Methylation index (MI) of each gene is presented for normal cervical sample (N) and cancer (T) as a boxplot. Whiskers of the boxplot mark the 5^th and 95^th percentiles, the box marks the 25^th (low boundary of box), median, and 75th (upper boundary of box) percentiles, and extreme values (●).
