The centiles and mean (SD) values were derived from the GAMLSS models for the exact ages shown.

*Number of grip strength observations refers to the number of individuals at age shown ±2.5 years (to give an indication of the sample size at different ages).

^†Limited data were available in the 95+ years category so centile values are not shown.
