Outcomes of Mice in the Early Hypertrophy Experimental Groups

Experimental Group	Control Sham	OGTKO Sham	Control TAC	OGTKO TAC
Number assigned to group	15	12	16	17
Intraoperative deaths	1	0	2	0
Postoperative death <48 h	0	0	1	0
Number completing protocol	14	12	13	17

The number assigned to group represents the starting population of mice that received the 4‐hydroxytamoxifen injections. Intraoperative deaths were from either arterial hemorrhage or intubation issues. No fatalities occurred >48 hours after surgery. OGTKO indicates O‐linked β‐N‐acetylglucosamine transferase knockout; TAC, transverse aortic constriction.
