Table 3.

Odds ratios for a change in handgrip strength by one Z-score, calculated within each country on the basis of age and measuring site

Z-scores	>+2	+2 to +1	+1 to –1 (reference group)	–1 to –2	<–2
Fallers with a fracture versus fallers with no fracture
Right-hand-grip strength	0.4 (0.1, 3.2)	0.7 (0.5, 1.6)	1.0	1.4 (0.9, 2.2)	2.6 (1.3, 5.2)
Fallers with a fracture versus non-fallers
Right-hand-grip strength	0.3 (0.1, 2.4)	0.8 (0.4, 1.3)	1.0	1.7 (1.1, 2.7)	3.9 (2.1, 7.4)
Fallers with no fracture versus non-fallers
Right-hand grip strength	0.7 (0.5, 1.1)	0.8 (0.7, 1.0)	1.0	1.2 (1.1, 1.4)	1.4 (1.1, 2.0)
