Results of Number of Significantly Overexpressed Transcripts (P < 0.05) for Each Class of Parathyroid Samples in a Multi-Class Supervised Comparison

Comparison	RecHPT versus NFH	Adenoma versus all others	FH versus all others	Nonfamilial MGN versus all others	Renal-induced hyperplasia versus all others	Normals versus all others

RecHPT = five cases of recurrent hyperparathyroidism; NFH = five cases initially diagnosed as primary parathyroid hyperplasia (nonfamilial hyperplasia); nonfamilial MGN = cases of recurrent hyperparathyroidism and nonfamilial hyperplasia grouped together; FH = three cases of MEN1 = related hyperparathyroidism.
