Ki-67 Staining in Mouse Models of Adrenal Tumors

Mouse model⁎	Tumors with given percentage of Ki-67+ cells (no.)				Total adrenals evaluated
	<1%	1%–5%	5%–10%	10–20%
Control (Cre−)	4	2	0	0	6
H19ΔDMD	6	2	0	0	8
APC KO	5	6	3	1	15
APC KO-H19ΔDMD†	0	10	2	2	14

^⁎Mantel-Haenszel chi-square analysis of linear association between all models: P = 0.0009.

^†Comparison of APC KO and APC KO-H19^ΔDMD by Mantel-Haenszel chi-square: P = 0.18.
