Table 3.

Pre- and post-operative visual analogue scale (VAS) and ODI scores and average stays for antero-posterior (AP) and anterior (A) groups

	VAS	ODI	Average stay (days)
AP pre-operative	6.5 (5–8)	60.2 (49–70)
AP post-operative	3.0 (2–4)^**	30.0 (25–41) ^**	21 (14–35)
A pre-operative	6.0 (5–8.5)	63.0 (45–68)
A post-operative	2.8 (2–4.5)^{, *}	28.5 (23–42) ^{, *}	15 (10–27)^*

*p < 0.05, significant difference, ** p < 0.05 within AP and A groups, respectively, significant difference, ***p > 0.05 between AP and A groups, no significant difference
