Are you serious? How about this part right here in the study title:

Caloric Restriction DELAYS Disease Onset AND MORTALITY in Rhesus Monkeys

...combined with the fact that in the contents of the study you link to, they eliminate significant data points whose presence would contradict the claimed delay in mortality.

I guess we'll all have to judge for ourselves whether it's fair to eliminate a bunch of deaths other than for exceedingly obvious reasons, e.g., someone breaks into the lab and kills the monkeys. I know which side I'm on.
