** Denotes that the isolated RNA contained degradation that has the potential to adversely affect the reliability of the results of the array. After the results of the hybridization signals were screened for evidence that signal patterns were adversely affected, some degraded specimens were affected adversely ( ¶ ), and some were not. See below.

¶ Denotes that the hybridization signal pattern of this sample was influenced by RNA degradation when it was analyzed. One or more outcomes were used to screen for anomalous hybridization on a particular chip. See 6.0 for details. Briefly, a hybridization signal was present in a relatively high percentage of all the probe sets, or signal intensities were weak across the board and required a high scaling factor for calibration. Both of those measures generally indicate that probe sets that did not produce a significant hybridization signal in most of the samples as a whole may erroneously report a signal being present on these particular chips. As well spiked control RNA may have shown an uneven distribution of cDNA representation due to uneven conversion to cDNA. This means that the effectiveness of hybridization of some transcripts on the chip, but not all transcripts on the chip, may have been corrupted due to RNA degradation. These errors can produce over- or under-representation of certain signal intensities relative to the other transcripts on the array.

** ¶ Both of the above

BOLD denotes that this case was added to compensate for cases that had preliminary evidence of potentially substantial RNA degradation
