Parathyroid tumor clonal status and pathology at discovered at surgery

Clonality	N	Operative Findings @ UE		Operative Findings @ BNE
		SGD	MGD	SGD	MGD
Monoclonal	43	16	0	24	3
Polyclonal	39	16	1	14	8*
Total	82	32	1	38	11

UE = unilateral exploration; BNE = bilateral neck exploration; SGD = single gland disease; MGD = multiple gland disease

^*P = 0.025 for MGD identified at BNE vs. UE
