Distribution of cp values of ECGs in different OS epithelial regions.

<p><a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0022301#pone-0022301-g001" target="_blank">Figure 1A</a>, the scatter graph of the Cp values of all the ECGs shows all the ECGs had cp value≤35. The order of samples 1–12 were as follows: Samples 1, 2, 3 were cornea 1, cornea 2, cornea 3, samples 4, 5, 6 were limbus 1, limbus 2, limbus 3, samples 7, 8, 9 were LEC 1, LEC 2, LEC 3 and samples 10, 11, 12 were conjunctiva 1, conjunctiva 2, conjunctiva 3. <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0022301#pone-0022301-g001" target="_blank">Figure 1B</a> is a box plot of q PCR cp values of the ECGs. Each box plot is mean Cp value of all OS epithelial regions. The median Cp value is represented as black line within the box plot, and it divides the Cp values into lower and upper quartile ranges. The whiskers represent the upper and lower data range for the samples tested. The box plot of PPIA demonstrates tight distribution of the samples around the median value. Similarly box plot of RPLP0 shows uniform distribution of Cp values around the median with tight whisker distribution.
