Platform sensitivity.

For each combination of platforms the identified miRNAs were used to calculate a weighted detection score based on the concordance of the two platforms (noted by “+” and “−”). The score took into account both the expression value of the individual miRNAs and detection by the other platforms that were not under investigation. The weighted score range from −1.0 (no agreement) to 1.0 (full agreement). Only miRNAs screened for in all platforms were included.
