TABLE 4.

Effect of C. chinensis and E. ulmoides on the lifespan of C. elegans.

Treatment	Mean lifespan		Min. [days]	Med. [days]	Max. [days]	n	p-value
	Days ± SE	%
Control	18.48 ± 0.4	100	14.71	17.61	26.00	275
E. ulmoides	20.19 ± 0.43	109.28	16.36	19.07	28.00	265	0.0065
C. chinensis	22.98 ± 0.47	124.39	18.50	22.50	31.00	225	<0.0001
Quercetin	21.90 ± 0.46	118.52	17.81	21.22	30.00	246	<0.0001

n, total number of worms; SE, Standard error; Min/Med/Max, minimum/median/maximum lifespan (days until deaths in population reached 25%/50%/100%). The p-values express significance using a log-rank test with subsequent Bonferroni correction.
