Means, standard deviations and p values, according to groups and days

Variable	Day	CM	NM	Inter-group differences
		Mean + SD	Mean + SD	(p)
% Mature collagen	3	10.5 ± 2.84	5.8 ± 2.66	*CM x NM
	7	38.3 ± 4.30	7.8 ± 2.15	***CM x NM
	14	100 ± 0	9 ± 2.98	***CM x NM
	21	100 ± 0	11 ± 2.98	***CM x NM
% Immature collagen	3	89.5 ± 2.84	94.2 ± 2.66	*CM x NM
	7	61.7 ± 4.30	92.2 ± 2.15	***CM x NM
	14	0 ± 0	91 ± 2.98	***CM x NM
	21	0 ± 0	89 ± 2.98	***CM x NM

Note:

^*p < 0.05,

^**p < 0.01,

^***p < 0.001 indicate statistically significant difference.

CM = induced movement/ NM = induced movement+nicotine / NS = non-significant.
