Effect of complexes 2 and 3 treatment on the survival of tumor-bearing mice^a.

Design of treatment	MST (in days)	ILS (%)
Tumour control	18.17 ± 0.87	—
5-FU	34.83 ± 0.91c,b	91.68
2	33.5 ± 1.12d,b	84.36
3	27.7 ± 0.88b	52.45

^a N = 6; data were expressed as mean ± SEM.

^b P < 0.001 vs. tumour control.

^c P < 0.001 vs. 5-FU.

^d P < 0.01 vs. complex 2; data were analysed by using one-way ANOVA followed by Tukey–Kramer multiple comparison test.
