RNA recoveries in the “Enriched CTC” fractions in melanoma patients vs. healthy controls.

There is a statistically significant difference between RNA yield levels of melanoma patients and the healthy controls (p = 0.005) based on the nonparametric Wilcoxon rank-sum test. There was no statistically significant correlation between melanoma stage and RNA yield. This was true for scale 1 (stage 1,2,3, or 4; p = 0.739) and scale 2 (where the scale separates 0, IA, IB, IIA, IIB, IIC, etc.; p = 0.948).
