Statistical Estimates of Survival Differences Between Control and Rapamycin-Treated Mice

	TJL male	UM male	UT male	Mean male	TJL female	UM female	UT female	Mean female
Control, median	800	851	780		889	891	843
Rapamycin, median	841	932	888		1077	1008	1006
% Change	5	10	14	10	21	13	19	18
Control, P90	1,002	1,061	985		1,064	1,061	1,101
Rapamycin, P90	1,155	1,211	1,167		1,220	1,211	1,204
% Change	15	14	18	16	15	14	9	13

Note: Estimates of median survival age or (P90) age at which 90% of the mice had died excluding mice removed from the study as defined in the Methods section. Percent change calculated as (rapamycin − control)/(control). Mean values are averages of the values calculated for each of the three test sites. UT = University of Texas; UM = University of Michigan; TJL = The Jackson Laboratory.
