All 3 mouse models were aged to 18 to 20 months. Mice that were used for experiments or euthanized for noncardiac causes were censored. Kaplan-Meier analysis with log-rank testing was then performed to identify differences in survival. Proportional hazard remaining constant was verified by using the Grambsch and Therneau test. cMyBP-C(t3SD) showed the best overall survival.
