Assessment changes(delta value)in the ASIA scores over time among the three groups of patients

	Motor	Pain	Light touch	Total score
ΔA	2.22 ± 4.18 (ab)	5.67 ± 4.64 (ab)	8.00 ± 6.78 (ab)	15.89 ± 13.93 (ab)
ΔB	7.78 ± 6.63 (ab, bc)	15.33 ± 10.00 (ab, bc)	16.89 ± 12.64 (ab, bc)	40.00 ± 27.48 (ab, bc)
ΔC	0.89 ± 1.17 (bc)	1.56 ± 2.60 (bc)	1.89 ± 3.40 (bc)	4.33 ± 6.34 (bc)
P value	0.009	0.001	0.004	0.001

Note: ab indicates that the comparison of the improvements in the scores between Group A and Group B yielded P < 0.05; bc indicates that the comparison of the improvements in the scores between Group B and Group C yielded P < 0.05.
