Table 2. Change of Pain in VAS, EQ-5D, EQ-5D VAS, and ODI.

100-mm VAS score	Aceclofenac CR (n=50)	In group	Aceclofenac (n=50)	In group	Between group
100-mm VAS score	Mean±SD	In group	Mean±SD	In group	Between group
Pre treat	58.2±14.0	p=0.028^*	64.0±13.1	p=0.013^*	p=0.075^†
Post treat	35.7±17.1		45.5±20.8		p=0.109^†
Alteration	22.6±15.8		18.6±17.7		p=0.145^†

CR, controlled release; VAS, Visual Analogue Scale; EQ-5D, EuroQoL 5D; EQ-5D VAS, EuroQoL 5D Visual Analogue Scale; ODI, Oswestry Disability Index.

Values of VAS and EQ-5D VAS are expressed as mean with standard deviation (SD). Values of EQ-5D and ODI are expressed as median with an inter-quartile range (IQR) in parenthesis. p<0.05: statistically significant.

^*Paired t-test: to compare VAS, EQ5D VAS of pre- and post-treatment in each group, ^†Unpaired t-test: to compare VAS, EQ5D VAS between aceclofenac CR and aceclofenac groups, ^‡Mann-Whitney U test: to compare EQ-5D, ODI change of pre-and post-treatment in each group, ^§Wilcoxon signed rank test: to compare EQ-5D, ODI change between aceclofenac CR and aceclofenac groups.
