Age-specific centile curves for handgrip strength, gait speed, and appendicular skeletal muscle mass
Smoothed age-specific centile curves for (A, D) handgrip strength, (B, E) gait speed, and (C, F) appendicular skeletal muscle mass index (ASM/height2) in women (A–C) and men (D–F), derived using Generalized Additive Models for Location, Scale, and Shape (GAMLSS). Lines represent selected centiles (5th, 15th, 20th, 50th, 75th, 85th, and 95th) across the age range from 40 years onward.
