Figure 10. Grip strength does not predict rotarod performance, dark phase activity or sleep fragmentation in 28-month-old mice. Visual representation of the relative performance on four healthspan measures by 28-month-old mice. Mice performing best (blue symbols) and worst (red symbols) on the grip strength test, did not perform similarly on other measures of healthspan in females (A) and males (B). Correlations and p-values are in Tables 2 and 3.
