Association Between Strength and Slow Gait Speed: Logistic Regression

	AGES-REYKJAVIK (N=2082)			Health ABC (N=919)
Men	Model 1	Model 2	Model 3	Model 1	Model 2	Model 3
Weak grip	4.43 (3.54–5.55)		3.43 (2.68–4.32)	2.90 (1.62–5.18)		2.16 (1.18–3.96)
Weak leg		5.77 (4.32–7.71)	3.59 (2.63–4.89)		3.92 (2.21–6.97)	3.21 (1.77–5.82)
C-statistic	0.67	0.61	0.71	0.63	0.66	0.71
Women	AGES-REYKJAVIK (N=2771)			Health ABC (N=994)
Weak grip	3.92 (3.27–4.70)		3.08 (2.55–3.73)	1.99 (1.11–3.58)		1.38 (0.75–2.53)
Weak leg		4.52 (3.66–5.58)	3.30 (2.64–4.12)		2.52 (1.71–3.71)	2.40 (1.61–3.58)
C-statistic	0.64	0.61	0.69	0.53	0.61	0.62

Model 1 tested grip strength alone, model 2 tested leg strength alone and model 3 tested both measures simultaneously.
