¹ Number of discriminating targets out of the 3.4 K set unique to platform which were available (not filtered) for all platforms (percentage relative to the total number of discriminating targets); of those the number (and percentage) that yielded a p value superior to 0.05 for each of the 2 other platforms. ² The number of targets uniquely not found to be discriminating and which were available (not filtered) for that platform (including the number of targets with a p value superior to 0.05 for that platform (percentage relative to the total of the uniquely not discriminating targets).
