Motor constructs and risk of adverse health outcomes^a

Predictor	Death, HR (95% CI)	ADb, HR (95% CI)	Disability, HR (95% CI)
Frailty	1.48 (1.27-1.73)	1.56 (1.27-1.92)	1.44 (1.21-1.71)
PSSc	1.53 (1.36-1.72)	1.35 (1.14-1.59)	2.20 (1.90-2.53)
GMSd	0.51 (0.42-0.60)	0.62 (0.49-0.78)	0.39 (0.32-0.47)

^aBased on proportional-hazard models that controlled for age, sex and education for each of the three outcomes. Results show the effect for 1 SD unit higher level of physical frailty (1 SD = 0.6 units), parkinsonian sign score (1 SD = 7 points) and global motor score (1 SD = 0.27 units). Higher baseline values for physical frailty and parkinsonian signs score (that is, poorer performance) were associated with an increased risk of adverse health outcomes (HR >1.00) whereas a higher baseline value for global motor score (that is, better performance) was associated with a decreased risk of adverse health outcomes (HR < 1.0).
