Effects of vitexin on the lifespan of C. elegans

Treatment	Mean Lifespan (day)	Maximum lifespan (day)	Change in mean lifespan (%)	Log-rank test
Control	13.5 ± 0.5	19	-	-
50 μM	14.6 ± 0.4	20	8.0	p<0.05*
100 μ M	15.8 ± 0.5	21	17.2	p<0.001***

Mean lifespan presented as mean ± S.E.M data. Change in mean lifespan compared with control group (%). Statistical significance of the difference between survival curves was determined by log-rank test using the Kaplan-Meier survival analysis. Differences compared to the control were considered significant at ^*p<0.05 and^***p<0.001.
