TABLE 4.

Mean difference of age- and sex-adjusted physical and mental scores in definite ET, probable/possible ET, and other tremor groups^a

Tremor group	N^b	N^b (ref. group)	Ref
Tremor group	N^b	N^b (ref. group)	Grip Strength (95% CI)	Cognitive Composite (95% CI)	ADL Strength Score (95% CI)
Definite ET	34	1,913	1.18 (−1.04; 3.40)	1.11^c (0.17; 2.05)	0.24^c (0.09; 0.39)
Possible/probable ET	65		0.02 (−1.92; 1.96)	0.16 (−0.69; 1.01)	0.11 (−0.02; 0.24)
Other tremors	17		−2.94^c (−5.24; −0.64)	−0.23 (−2.15; 1.68)	−0.39 (−0.79; 0.00)

ET, essential tremor; AL, activitie of daily living.

The results demonstrate that ET and probable ET patients have better aging outcomes than the control population but the other tremors not.

P< 0.05.

The numbers vary because of missing information in outcome variables.

Control group: Not ET-cases among neurological assessed and individuals who did not have a neurological assessment.
