Table 2.

Number of animals in the lowest 20% for each parameter and 5% for body weight, used to calculate frailty score. The frailty score for each experimental group was calculated as follows: total number of tests failed by the animals at each experimental group divided by the total number of tests performed by those animals, expressed in percentage.

Age		4-month-old		8-month-old
		DMSO	18αGA + n-3FA	DMSO	18αGA + n3FA
Number of animals in the lowest 20%	Distance traveled (cm)	4	0	2	0
	Vertical activity (beams)	3	1	2	1
	Velocity (cm/sec)	2	2	1	2
	Ambulatory time (sec)	4	0	3	0
	Total time spent in moving (%)	4	0	3	0
	Grip test	1	1	0	2
	Rope test	1	0	0	2
	Weight in the lowest 5% (g)	1	0	2	0
Total number of animals that failed the tests (A)		20	4	13	4
Total number of tests performed (B)		60	82	43	57
(A/B)		0.333	0.0488	0.302	0.071
Frailty score (A/Bx100)		33.333	4.878	30.230	7.010
