Vastus lateralis muscle thickness

1. Vastus lateralis muscle thickness has no effect on mortality in humans.

   “US-MT was not associated with trajectories of physical performance or with LOS, falls, or mortality.”

1. Vastus lateralis muscle thickness is associated with 30-s Sit-to-Stand in humans (IRR 1.24; 95% CI 1.00-1.53).

   “with better 30s STS performance across sexes (IRR 1.24; 95% CI 1.00-1.53) across all time points.”

1. Vastus lateralis muscle thickness is associated with gait speed in humans (0.037 m/s; 95% CI 0.022-0.051).

   “Greater admission US-MT was modestly associated with faster GS in women (0.037 m/s; 95% CI 0.022-0.051)”
