Table 1.

Changes in the physical activity of animals as a percentage of the initial value.

	Start	End of Injection	1st Month	2nd Month
Control	100%	87%	79%	94%
DOX	100%	65% *	55% *	50% *
NR+DOX	100%	61%*	64% *	58% *
NR/NR+DOX	100%	80%	71%	69%

DOX represents doxorubicin; NR represents nicotinamide riboside. *—p < 0.05, significant difference compared to the initial value (start of the experiment). Control represents control group (n = 15); DOX represents doxorubicin group (n = 15); NR+DOX represents nicotinamide riboside + doxorubicin group—combined mode (n = 15); and NR/NR+DOX represents nicotinamide riboside/nicotinamide riboside + doxorubicin group—preventive mode (n = 15).
